Detection, Isolation and Confirmation of Crimean-Congo Hemorrhagic Fever Virus in Human, Ticks and Animals in Ahmadabad, India, 2010–2011
A nosocomial outbreak of CCHFV occurred in January 2011, in a tertiary care hospital in Ahmadabad, Gujarat State in western India. Out of a total five cases reported, contact transmission occurred to three treating medical professionals, all of whom succumbed to the disease. The only survivor was the husband of the index case. These results highlight the importance of considering CCHFV as a potential aetiology for Hemorrhagic fever (HF) cases in India. This also underlines the need for strict barrier nursing and patient isolation while managing these patients. During the investigation presence of CCHFV RNA in Hyalomma anatolicum ticks and livestock were detected in the village from where the primary case (case A) was reported. Further retrospective investigation confirmed two CCHF human cases in Rajkot village 20 kilometres to the west of Ahmadabad in 2010, and CCHFV presence in the livestock 200 kilometres to the north in the neighbouring State Rajasthan. This report shows the presence of CCHFV in human, ticks and animals in Gujarat, India. The fact of concern is the spread of this disease from one state to another due to trading of livestock

The Effect of expanded polystyrene and cement on properties of sand soils for foundation use
This is a proceeding paper presented at 17th African Regional Conference on Soil Mechanics and Geotechnical Engineering on the effects of expanded polystyrene and cement on properties of sand soils for foundation use.The increase in Expanded Polystyrene (EPS) waste in Uganda is prone to cause serious environmental pollution owing to the related poor disposal methods. The common practices include open disposal and/or burning which are both environmentally degrading. Other approaches of recycling EPS are unpopular and quite expensive. This research aimed to investigate the effect of EPS and cement on sand soil for a foundation material. The soil was a poorly graded sand. Preliminary tests were carried out to determine the grading,
Optimum Moisture Content (OMC) and Maximum Dry Density (MDD) of the sand. Initial cement consumption test was done to determine a constant weight of cement required for just the binding effect on the materials.
The unconfined compressive strength, shear box, permeability and consolidation tests were performed on the treated soil specimens at various percentages of EPS. The sand-EPS-cement composite showed an increase in unconfined compressive strength and shear strength with the maximum at 0.5% EPS. The permeability of the composite decreased while there was a minimal increase in settlement with increasing EPS content

Drivers of farm business capital structure and its speed of adjustment: evidence from Western Australia’s Wheatbelt
The viability and profitability of a farm business can be influenced by how it chooses to fund its operations and capital investments either using debt or internal funds. This study examines the determinants and speed of adjustment of the capital structure of broadacre farm businesses in Western Australia’s Wheatbelt. Results show that prior period cash flow and equity, farm size and farm location are significant determinants of observed capital structures. Farm businesses are found to quickly adjust their capital structure to desired target levels, suggesting that adjustment costs are not high. The findings support the view that there is a pecking order in the choice of how farm businesses fund working capital and capital investments

Accounting for drinking water quality in measuring multidimensional poverty in Ethiopia.
The Multidimensional Poverty Index is used increasingly to measure poverty in developing countries. The index is constructed using selected indicators that cover health, education, and living standards dimensions. The accuracy of this tool, however, depends on how each indicator is measured. This study explores the effect of accounting for water quality in multidimensional poverty measurement. Access to drinking water is traditionally measured by water source types. The study uses a more comprehensive measure, access to safely managed drinking water services, which are free from E. coli contamination, available when needed and accessible on premises in line with Sustainable Development Goal target 6.1. The study finds that the new measure increases national multidimensional headcount poverty by 5-13 percentage points, which would mean that 5-13 million more people are multidimensionally poor. It also increases the poverty level in urban areas to a greater extent than in rural areas. The finding is robust to changes in water contamination risk levels and Multidimensional Poverty Index aggregation approaches and weighting structures
Fluoride Levels in Water, Animal Feeds, Cow Milk, Cow Urine and Milk Production of Dairy Cattle from Kiambu and Thika Districts in Kenya
Kiambu and Thika Districts are situated in Central part of Kenya. Most of the available land is suitable for agricultural use. Majority of the farmers are small scale or subsistence dairy farmers. Intake of excess fluoride in water, feed and mineral supplements may adversely affect health, reproduction and production in dairy cattle. The objectives of this study were to investigate the levels of fluoride in water, urine, milk and animal feeds and mineral salts from dairy farms in Kiambu and Thika, as well as to relate milk yield and fluoride intake. Samples were analyzed using electroanalysis technique. The overall mean fluoride concentration in feeds from societies was 60.9 + 132.0 mg F/kg. The mean fluoride concentration in feeds from Nderi, Kikuyu, Chania, Limuru, Kiambaa and Lari co-operative societies were: 19.5 +11.3 (n=19) 24.1+28.6 (n=22), 55.2+73.7 (n=18), 67.6+93.4 (n=15), 91.9+226.3 (n=24) and 203.4+ 243.2 (n=6) mg F/kg respectively. Individual dairy co-operative society and the type of sample significantly (
A Model-based Approach for Determining Optimal Lime Application Rate and Frequency
Soil acidification reduces land productivity across agricultural systems worldwide. The standard remedy is to periodically apply lime to the soil surface which, over a number of years, is assimilated into the soil profile and raises soil pH. Lime applications can be viewed as an investment in soil productivity. This paper presents a dynamic model to determine an optimal lime application for a cereal crop. The results for the Western Australian Wheatbelt using wheat as an indicator of soil productivity, show that optimal application rate and frequency vary with rainfall and initial soil pH. Incorporating lime through the soil profile increases net present value by up to 6% compared to traditional surface lime applications and reduces lime application rates and required time for soil acidity amendment
