This article analyzes the process of forest fragmentation of a floodplain landscape of the Lower Amazon over a 30-year period and its implications for the biodiversity and the provision of ecosystem services to the riverine population. To this end, we created a multi-temporal forest cover map based on Landsat images, and then analyzed the fragmentation dynamics through landscape metrics. From t...

Demand for agricultural food production is projected to increase dramatically in the coming decades, putting at risk our clean water supply and prospects for sustainable development. Fragmentation-free land allocation (FF-LA) aims to improve returns on ecosystem services by determining both space partitioning of a study area and choice of land-use/land-cover management practice (LMP) for each p...

Current approaches to fragmentation of services are not businessoriented. They are not based on a real temporal query language, and in general, they return execution traces instead of parts of the process. We propose in this work an approach for fragmentation based on model checking and slicing techniques. Fragmentation is based on business rules expressed in LTL. In our work the fragmentation ...

Active network is an excellent paradigm to provide customized network services to the applications by allowing them to inject specific program to the intermediate routers. Active networks provide the flexibility for the application programs to modify the services that a router can provide to suit its specific needs. Therefore, it has the potential to provide application-level quality of service...

Landscape dynamics are common phenomenon in the human-dominated environments whereby it can be observed that the composition and configuration between landscape elements change over time. This dynamism brings about habitat loss and fragmentation that can greatly alter ecosystem services at patch, class, and landscape levels. We conducted a study to examine composition and configuration of fores...

Background Sperm DNA fragmentation is known as an important cause of male infertility. The influence of sperm DNA damage on reproductive potential has been subject of many studies indicating various results and remaining the subject controversial. In this study, we investigated differences of the semen parameters and intracytoplasmic sperm injection (ICSI) outcome according to sperm DNA fragmen...
