OBJECTIVE To isolate and identify Cryptococcus from domestic Chicken dropping. DESIGN cross sectional study. SETTING Kabigeriet village, Olenguorone Division, Nakuru county, approximately 282 km from Nairobi, Kenya. SUBJECTS Sixty four domestic chicken droppings were sampled in thirty two homesteads after obtaining the farmers consent. RESULTS Two species of Cryptococcus were isolated. ...

In response to predation pressure, some insects have developed spectacular plant mimicry strategies (homomorphy), involving important changes in their morphology. The fossil record of plant mimicry provides clues to the importance of predation pressure in the deep past. Surprisingly, to date, the oldest confirmed records of insect leaf mimicry are Mesozoic. Here we document a crucial step in th...

A cDNA encoding flavone synthase I was amplified by RT-PCR from leaflets of Petroselinum crispum cv. Italian Giant seedlings and functionally expressed in yeast cells. The identity of the recombinant, 2-oxoglutarate-dependent enzyme was verified in assays converting (2S)-naringenin to apigenin.

Working memory is a fundamental cognitive building block involved in the short-term maintenance and transformation of information. In neuropsychological studies, working memory has been shown to be of limited capacity; however, the neurophysiological concomitants of this capacity limitation have not been explored. In this study we used the [15O] water PET rCBF technique and statistical parametr...

Chapter 1 introduced the index and indicator concept and outlined a number of microorganisms (and groups of microorganisms) that have been adopted in the quest to determine whether or not drinking water is microbiologically safe to drink. This chapter examines the range of both microbial and non-microbial parameters and briefly outlines their uses and applications. It is intended to act as an i...

We investigated a new kind of activated carbon named gaiasafe-Formstoff as an agent for powerful heavy metal reduction. This activated carbon contains highly dispersed sulfide compounds. Our investigations with lead containing wastewaters showed an outstanding metal sulfide precipitation power of the new agent. The lead reduction rates are independent of wastewater parameters like lead concentr...

In this paper, we present the role of remote sensing technology in the context of the monitoring of surface water status within the European union (EU) water framework directive (WFD). Although the digital evaluation of remotely sensed data has been used to estimate surface water characteristics for over two decades, there are still few discussions available on the contribution of remote sensin...

This study aims at quantification of health losses, considering social and environmental factors. Morbidity and mortality cases of diarrhoea for children under five years old were used to estimate the disability adjusted life years (DALYs) lost for the target households in low-income communities in Dhaka, Bangladesh. Water supply facilities and sanitation systems, along with hygiene practices a...

Performing a multiscale assessment of water resource vulnerability on the basis of political boundaries and watersheds is necessary for adaptive water resources management. Using the Risk-Exposure-Sensitivity-Adaptability model (RESC model), the water resource vulnerability of the Huai River Basin was assessed using four scales, namely, Class II, Class III, Province-Class II, and Municipality-C...

Community water supply programmes in developing countries frequently utilise wells or boreholes equipped with handpumps as the technology of choice. Whilst simple targets concerning numbers of wells to be drilled, or villages to be served, are often prominent, the wider objectives of such programmes are rarely expressed in quantified terms, and as a consequence programme impact is often disappo...
