Coccidiosis is a protozoan disease in chickens caused by Eimeria spp with great economic significance. The disease can be controlled by using modern anticoccidial drugs. However large scale and long term use of anticoccidial drugs has led to the resistance. Phytotherapy can be used successfully as an alternative coccidiosis control strategy. Ninety six chicks experimentally infected with coccidiosis were used in the present study. The chicks were divided into 24 groups and were treated with the crude watery extract (10%) of mango, pineapple, guava, chutra leaves and thankuni at the dose rate of 1ml, 5ml and 10ml per Kg body weight as well as one group was treated with Embazine® at recommended dose. The effects of these drugs were evaluated by oocyst count from faecal sample and the mortality rate. The result shows that the 10ml/Kg dose worked better than other dose. In this dose oocyst count significantly decreased (P< 0.01) at the day of 4 (mango), 2 (pineapple), 12 (guava), 2 (chutra) and 4 (thankuni). No oocyst found in feces at the day 8 (chutra and thankuni), 12 (mango and pineapple) whereas on day 12 it shows oocyst in feces in case guava. It shows that mortality encounter 75% in mango and guava group, 50% in pineapple and thankuni group, wheras no mortality recorded in chutra group. After completion of experiment it was noted that chutra leaves was most effective at the dose rate of 10 ml/kg body weight and effective near about Embazine.Res. Agric., Livest.

To cooperate effectively, both in small-scale interactions and large-scale collective-action problems, people frequently have to delay gratification (i.e., resist short-term temptations in favor of joint long-term goals). Although delay-of-gratification skills are commonly considered critical in children’s social-cognitive development, they have rarely been studied in the context of cooperative decision-making. In the current study, we therefore presented pairs of children ( N = 207 individuals) with a modified version of the famous marshmallow test, in which children’s outcomes were interdependently linked such that the children were rewarded only if both members of the pair delayed gratification. Children from two highly diverse cultures (Germany and Kenya) performed substantially better than they did on a standard version of the test, suggesting that children are more willing to delay gratification for cooperative than for individual goals. The results indicate that from early in life, human children are psychologically equipped to respond to social interdependencies in ways that facilitate cooperative success.

After the Fukushima Daiichi accident, there have been long controversial discussions on “how safe is safe?” between the authorities and the residents in the affected area. This controversy was partly attributable to the way the authorities made a judgement based on the annual effective dose rate; meanwhile, many of the local residents have serious concerns about future consequences for their health caused by chronic radiation exposure, particularly of small children. To settle this controversy, the author presents an approach based on long-term cancer risk projections of female infants, i.e., the most radiosensitive group, following land contamination by radiocesium deposition into ground with different surface conditions; the land was classified into three categories on the basis of decaying patterns of radiation dose rate: “Fast”, “Middle”, and “Slow”. From the results of analyses with an initial dose rate of 20 mGy per year, it was predicted that the integrated lifetime attributable risk (LAR) of cancer mortality of a female person ranged by a factor of 2 from 1.8% (for the Fast area) to 3.6% (for the Slow area) that were clearly higher than the nominal risk values derived from effective dose estimates with median values of environmental model parameters. These findings suggest that accurate site-specific information on the behavioral characteristics of radionuclides in the terrestrial environment are critically important for adequate decision making for protecting people when there is an event accompanied by large-scale radioactive contamination.

Abstract. In this paper, we present our approach for robust long-term visual localization in large scale urban environments exploiting street level imagery. Our approach consists of a 2D-image based localization using image retrieval (NetVLAD) to select reference images. This is followed by a 3D-structure based localization with a robust image matcher (DenseSfM) for accurate pose estimation. This visual localization approach is evaluated by means of the ‘Sun’ subset of the RobotCar seasons dataset, which is part of the Visual Localization benchmark. As the results on the RobotCar benchmark dataset are nearly on par with the top ranked approaches, we focused our investigations on reproducibility and performance with own data. For this purpose, we created a dataset with street-level imagery. In order to have independent reference and query images, we used a road-based and a tram-based mapping campaign with a time difference of four years. The approximately 90% successfully oriented images of both datasets are a good indicator for the robustness of our approach. With about 50% success rate, every second image could be localized with a position accuracy better than 0.25 m and a rotation accuracy better than 2°.

In the article, the authors analyze the current state and prospects for the development of the transport infrastructure in the countries of East Africa. They provide latest data on projects in pipeline. Today, Africa is a dynamically developing continent with powerful economic, demographic and resource potential that will have a tangible impact on world development in the 21st century. The large-scale transformations that are taking place on the continent require an outstripping pace of infrastructure development, which, despite the success achieved, still does not meet its needs. While total capital investment in infrastructure projects in African countries in 2018 reached record level, the lack of funding remains one of the key obstacles for the development of African infrastructure. The COVID-19 pandemic that swept the world in 2020 will further exacerbate the existing gap between investment needed and investment required. The economic potential of many infrastructure projects will decline. However, according to the authors, the negative impact will not be so large-scale due to the long-term nature of the contracts, as well as the socio-economic significance of the projects. The authors of the article come to the conclusion that in the context of an epidemiological crisis, both national and foreign investors who invest in the development of regional infrastructure seek to share their risks by attracting new financial partners. This situation opens up additional opportunities for Russian companies and enterprises to enter long-term and capital-intensive infrastructure projects in East Africa, which can become a solid basis for building Russian-African economic relations.

Catharanthus roseus (Nyantara), Azadirachta indica (Neem), Allium sativum (Garlic) are medicinal plants, used in Ayurveda for treating various diseases, one of which is diabetes mellitus. In the present study of 12 months period from January to December 2007, aqueous extract of this plants were prepared and blood glucose lowering effect and improvement of body weight gain in Streptozotocin (50 mg/kg bwt i.p.) induced diabetic rats were measured and compared with that of a patent drug glimepride in the Department of Pharmacology, Bangladesh Agricultural University, Mymensingh. Rats were administered Catharanthus roseus, Azadirachta indica, Allium sativum extracts at the dose rate of 1g/kg, 500 mg/kg and 1g/kg bwt orally for 14 days, respectively. Blood glucose level and body weight was measured by Glucotrend kit and Electronic balance and that compared with a patent drug Glimepride at a dose rate of 100 mg/kg bwt. The data were compared statistically by using student's unpaired t-test. The herbal preparations of these plants significantly increased body weight gain and decreased blood glucose as compared with the patent drug. The present study clearly indicated the significant antidiabetic activity of Catharanthus Roseus, Azadirachta indica and Allium sativum and supports the traditional usage of the herbal preparations by Ayurvedic physicians for the therapy of diabetics.

AbstractThe large-scale coronal structures observed during the sporadically visible solar eclipses were compared with the numerically extrapolated field-line structures of coronal magnetic field. A characteristic relationship between the observed structures of coronal plasma and the magnetic field line configurations was determined. The long-term evolution of large scale coronal structures inferred from photospheric magnetic observations in the course of 11- and 22-year solar cycles is described.Some known parameters, such as the source surface radius, or coronal rotation rate are discussed and actually interpreted. A relation between the large-scale photospheric magnetic field evolution and the coronal structure rearrangement is demonstrated.

Computer Analyses

The utilization of an automated multitest laboratory as a data acquisition center and of a computer for trie data processing and analysis permits large scale preventive medical research previously not feasible. Normal test values are easily generated for the particular population studied. Long-term epidemiological research on large numbers of persons becomes practical. It is our belief that the advent of automation and computers has introduced a new era of preventive medicine.
