This study was conducted to explore the ecosystem services of urban forests in Adama city, central Ethiopia. Attempts were made quantify carbon storage and sequestration, air pollution removal hydrological benefits trees. The forest structure composition city surveyed analyzed. i-Tree Eco Model employed analyze based on current city. result revealed that trees stored a total 116,000 tons carbon...

DNA molecules cut with endonuclease R Eco Ri can be joined at Eco Ri cleavage sites by incubation with polynucleotide ligase. In order to define the optimum conditions for this reaction, linear Simian Virus 40 DNA molecules (SV40(Lri)) produced by endonuclease R Eco Ri cleavage of SV40 form i DNA were joined using polynucleotide ligases specified by bacteriophage T4 and Escherichia coli. We hav...

Calf satellite DNA I (p = 1.715) has been hydrolysed by a number or restriction endonucleases. It consists of a repeating unit of 1460 nucleotide pairs within which the sites of Eco R II Mbo I, Sac I, Alu I, Ava II and Hha I were localised in comparison with those of Eco R I and Hind II. The distribution of the Hpa II, Sac I, Hha I, Hinf I and Mbo II sites within calf satellite DNA I, as well a...

Customer feedback is used to understand customer requirements. Early design phases require the consideration of items including manufacturing, the environment, and sustainability management. Therefore, it is crucial that eco-efficiency is taken into account in the early design phases. Traditionally, eco-efficiency is considered only in terms of eco-design issues, not customer requirements based...

Three DNA restriction fragments of established sequence containing the Escherichia coli lac genetic controlling regions were cloned. In each case a recombinant plasmid was constructed which was suitable for the subsequent large scale purification of the lac fragment. A 789-base pair HindII fragment, containing the lac operator, promoter, and cyclic AMP receptor protein binding site, was ligated...

Research in ecology and evolutionary biology (evo-eco) often tries to emulate the “hard” sciences such as physics and chemistry, but to many of its practitioners feels more like the “soft” sciences of psychology and sociology. I argue that this schizophrenic attitude is the result of lack of appreciation of the full consequences of the peculiarity of the evo-eco sciences as lying in between a-h...

Mounting research highlights the contribution of ecosystem services provided by urban forests to quality of life in cities, yet these services are rarely explicitly considered in environmental policy targets. We quantify regulating services provided by urban forests and evaluate their contribution to comply with policy targets of air quality and climate change mitigation in the municipality of ...

BACKGROUND Chagas disease transmission by Triatoma dimidiata persists in Guatemala and elsewhere in Central America under undefined ecological, biological and social (eco-bio-social) conditions. METHODOLOGY Eco-bio-social risk factors associated with persistent domiciliary infestation were identified by a cross-sectional survey and qualitative participatory methods. Quantitative and qualitati...
