    One of the internet service used by the people of Indonesia is a blog that can be accessed via http://blogspot.com or http://wordpress.com and others. Everyone can use this medium for the purpose of publication of information in the form of text, images, sounds, or video without having to master web programming languages. One of the obstacles a person who has a blog is a way of increasing number of visitors to his blog. In order for many visitors the blog owner needs to understand about SEO (Search Engine Optimization).To allow users to blog in increasing the number of visitors and ranking his blog, they invented a system that utilizes parallel processing techniques and create a new method, named TSC (Together in a Single Connection) to increase the number of visitors, number of pages viewed and ranking.Increase blog traffic system based on parallel processing can improve the effectiveness in increasing traffic to a blog. With this system the blog owner is expected to be easier to rise to visit his blog

    Topsoil is a valuable resource to humankind. Current food production cannot be continued without this resource. Topsoil protection efforts must be continued or increased to meet future demands of mankind. Erosion reduces productivity but losses may not be detected until land is no longer suitable to produce crops economically, furthermore, other variables may mask the relationship. Technology advancement including improved seed varieties, modern fertilizer, and herbicide have doubled or tripled many North American crop yields in the past 50 years. The impact of topsoil removal is largely determined by subsoil properties as they affect root growth, soil available water and nutrient availability in the soil. A new soil environment is encountered when topsoil is removed either by natural or artificial erosion. This new environment in most cases is less suited for plant growth than original topsoil. Germination and emergence are often poor because of less than ideal soil physical properties. Topsoil loss may alter root system growth. The potential for nutrient and water uptake consequently depends on the new level of soil nutrients and available water surrounding the root system, and the morphology of the root system. Topsoil removal may change resistance of surface aggregates to the beating action of raindrops. The stability of surface aggregates is important because aggregates below the surface are protected from rapid wetting by those above. Unstable surface aggregates are easily broken down and transported in suspension. This can lead to the formation of crusts that inhibit the movement of water and air into the soil. Maridasan and Chibber obtained a significant negative correlation between aggregate stability and the erosion ratio. Furthermore, aggregate stability influences plant growth indirectly through its relationship to the maintenance of a porosity suitable for air, water, and root movement. Recently, researchers have devoted considerable effort to quantify the relationship between topsoil removal and soil productivity, principally on the basis of data from the North Central Region of the United States. The objectives of this study were: (1) to determine the effects of erosion and desurfacing on soil physical and chemical properties. (2) to examine the relationships of aggregate stability (a measure of soil structural stability) with soil properties which result from the erosion and desurfacing of a Beadle Tax adjunct (Fine, montmorillonitic, mesic Typic Haplustoll). (3) to assess and compare the effect of erosion and desurfacing on continuous corn yield for this soil in eastern South Dakota

    Impact of land use/cover change and slope gradient on soil organic carbon stock in Anjeni watershed, Northwest Ethiopia

    Today’s agri-food systems face the triple challenge of addressing food security, adapting to climate change, and reducing the climate footprint by reducing the emission of greenhouse gases (GHG). In agri-food systems, changes in land use and land cover (LULC) could affect soil physicochemical properties, particularly soil organic carbon (SOC) stock. However, the impact varies depending on the physical, social, and economic conditions of a given region or watershed. Given this, a study was conducted to quantify the impact of LULC and slope gradient on SOC stock and C sequestration rate in the Anjeni watershed, which is a highly populated and intensively cultivated area in Northwest Ethiopia. Seventy-two soil samples were collected from 0–15 and 15–30 cm soil depths representing four land use types and three slope gradients. Soil samples were selected systematically to match the historical records (30 years) for SOC stock comparison. Four land use types were quantified using Landsat imagery analysis. As expected, plantation forest had a significantly (p \u3c 0.05) higher SOC (1.94 Mg ha−1) than cultivated land (1.38 Mg ha−1), and gentle slopes (1–15%) had the highest SOC (1.77 Mg ha−1) than steeper slopes (\u3e 30%). However, higher SOC stock (72.03 Mg ha−1) and SOC sequestration rate (3.00 Mg ha−1 year−1) were recorded when cultivated land was converted to grassland, while lower SOC stock (8.87 Mg ha−1) and sequestration rate (0.77 Mg ha−1 year−1) were recorded when land use changed from cultivation to a plantation forest. The results indicated that LULC changes and slope gradient had a major impact on SOC stock and C sequestration rate over 30 years in a highly populated watershed. It is concluded that in intensively used watersheds, a carefully planned land use that involves the conversion of cultivated land to grassland could lead to an increase in soil C sequestration and contributes to reducing the carbon footprint of agri-food systems

    Disorders of sex development : timing of diagnosis and management in a single large tertiary center

    Background: We describe the phenotypic spectrum and timing of diagnosis and management in a large series of patients with disorders of sexual development (DSD) treated in a single pediatric tertiary center. Methods: DSD patients who had visited our tertiary center during the survey period (between 2004 and 2014) were identified based on an ICD-10 inquiry, and their phenotypic and molecular genetic findings were recorded from patient charts. Results: Among the 550 DSD patients, 53.3% had 46,XY DSD; 37.1% had sex chromosome DSD and 9.6% had 46,XX DSD. The most common diagnoses were Turner syndrome (19.8%, diagnosed at the mean age of 4.7 +/- 5.5 years), Klinefelter syndrome (14.5%, 6.8 +/- 6.2 years) and bilateral cryptorchidism (23.1%). Very few patients with 46,XY DSD (7%) or 46,XX DSD (21%) had molecular genetic diagnosis. The yearly rate of DSD diagnoses remained stable over the survey period. After the release of the Nordic consensus on the management of undescended testes, the age at surgery for bilateral cryptorchidism declined significantly (P <0.001). Conclusions: Our results show that (i) Turner syndrome and Klinefelter syndrome, the most frequent single DSD diagnoses, are still diagnosed relatively late; (ii) a temporal shift was observed in the management of bilateral cryptorchidism, which may favorably influence patients' adulthood semen quality and (iii) next-generation sequencing methods are not fully employed in the diagnostics of DSD patients.Peer reviewe
