one very decisive factor in students’ academic destiny is the result they get at final term examinations. because of its importance, both students and teachers are curiously anxious about them. as normally it is the case, these final term tests are prepared hurriedly in short time by teachers which result in students’ dissatisfaction, complaining on how the test was different from their expecta...
Kane County is located on the western fringe of the greater Chicago metropolitan area. Development pressures there have caused rapid increases in land consumption and property values. The county’s Forest Preserve District is actively purchasing land for conservation, but it is important to understand the long-term costs associated with current conservation goals. We developed 18 future scenario...
Numerous protected areas (PAs) have been created in Africa to safeguard wildlife and other natural resources. However, significant threats from anthropogenic activities and decline of wildlife populations persist, while conservation efforts in most PAs are still minimal. We assessed the impact level of the most common threats to wildlife within PAs in tropical Africa and the relationship of con...
Evaluation of the ecological sustainability of different cropping systems is crucial to achieve sustainable agriculture. This evaluation is accessible via soil quality assessment. Therefore, to study the mid-term effects of different conservation tillage systems (no tillage and minimum tillage) and cover cropping on the biological indicators of soil quality, a factorial experiment in a complete...
Mountain vipers of the genus Montivipera, generally, and the species of the Raddei clade, specifically, are interesting examples of species neo-endemism in Iran, Anatolia, and the Caucasus. Given the critical conservation status of these species, it is necessary to identify their suitable habitats for prioritizing conservation measures. We modeled ecological niche of each species based on four ...
The latest tiger census conducted in India during the year 2014 shows that it harbors 57% of the global tiger population in 7% of their historic global range. At the same time, India has 1.25 billion people growing at a rate of 1.7% per year. Protected tiger habitats in India are geographically isolated and collectively holds this tiger population under tremendous anthropogenic pressure. These ...
Humans are altering their living environment to an extent that could cause environmental collapse. Promoting change into environmental sustainability is therefore urgent. Despite a rapid expansion in conservation biology, appreciation of underlying causes and identification of long-term solutions have largely been lacking. I summarized knowledge regarding the environmental crisis, and argue tha...
BACKGROUND: Radiation therapy is a key component of breast conservation therapy for breast cancer. There is great interest in safety and long-term outcome issues for this still underutilized approach. METHODS: The author reviews a series of factors that may affect the end results of conservation therapy and highlights those that are likely to be of clinical significance. RESULTS: Daily dose fra...
In one dimensional codes, a cross section area variation versus the duct length can produce important mass conservation errors when the gas-dynamic through the ducts of an internal combustion engine (ICE) is modelled. The CE-SE scheme (Conservation Element-Solution Element) is a numerical method that combines accuracy and speed in constant section ducts, but it presents a lack in mass conservat...
This report describes the results of interviews and focus groups, gauging support for innovative farmland preservation techniques. Four techniques were selected for assessment from approximately 30 novel techniques identified in previous research: (1) Term conservation easements; (2) Land preservation tontines; (3) Rights of first refusal; and (4) Agricultural conservation pension with purchase...
