  • Mathematical modelling is the process of formulating an abstract model in terms of mathematical language to describe the complex behaviour of a real system. Mathematical models are quantitative models and often expressed in terms of ordinary differential equations and partial differential equations. Mathematical models can also be statistical models, fuzzy logic models and empirical relationships. In fact, any model description using mathematical language can be called a mathematical model.

  • Mathematical Modeling I – preliminary is designed for undergraduate students. Two other followup books, Mathematical Modeling II – advanced and Mathematical Modeling III – case studies in biology, will be published. II and III will be designed for both graduate students and undergraduate students. All the three books are independent and useful for study and application of mathematical modeling in any discipline.

  • each year some eight million of the estimated 210 million women who become pregnant, suffer life- threatening complications related to pregnancy. in 2000, an estimated 529,000 women died during pregnancy and childbirth from largely preventable causes; 2.7 million infants are stillborn every year and three million infants die within the first seven days of life. globally, the maternal mortality ratio has not changed over the past decade. Ninety-nine percent of all maternal deaths occur in developing countries16 . Somalia has one of the highest maternal mortality ratios in the world.

  • Technical notes (on page 331) provide information detailing the specific data sources for key indicators as well as guidance for the interpretation of the statistics. Official United Nations estimates are used for all MDG indicators. These figures are supplemented, as necessary, by additional standard data sources. Information on social and political contexts and policy priorities have been obtained from UNFPA country offices and standard United Nations reports.

  • The total number of mammalian cortical granule proteins has been estimated to be between four and fourteen or more [10,19,20]. Several specific proteins have been iden- tified as cortical granule proteins [21]. N-acetylglucosami- nidase was detected in exudates of ionophore-activated mouse oocytes using an enzymatic assay and was local- ized in the cortical granules at the electron microscopic level [13].

  • An animal bite that breaks or punctures the skin has a significant chance of producing a bacterial infection. If any wild animal or pet bites and breaks the skin, the wound should be evaluated by a healthcare professional. Animal bites are common and bites of some animals (e.g. stray dogs, raccoons, bats) may transmit the rabies virus. Rabies is a very serious viral infection that infects the nervous system. Rabies is transmitted by a variety of wild animals. The virus can also be spread by unimmunized pets and in rare cases, immunized pets that have been...

  • Before the Modular Wetlands Device was installed, the boat wash water was treated by StormCeptor vaults installed in 2003. After installation, bacteria levels still exceeded action levels. Further attempts to reduce bacteria levels resulted in a pilot study conducted by the City of Oceanside. According to the Bacterial Reduction Pilot Program – Oceanside Harbor, XTEX AM antimicrobial fabric filters were installed on the separator vaults in addition to more frequent cleaning of the boat wash out separation vaults and drains as part of the study.

  • Almost all of the 250 MSM surveyed knew that HIV/AIDS could be contracted through sexual intercourse and 80 percent cited condoms as a way to prevent the disease, although actual use does not reflect knowledge. Many respondents reported having experienced STI-related symptoms. For example, 42 percent had had burning or penile discharge and 22 percent reported having had lesions or pustules on their anus (Table 2).

  • All people, including those living in humanitarian settings, have the right to reproductive health (RH). To exercise this right, affected populations must have an enabling environ- ment and access to comprehensive RH information and services so they can make free and informed choices. Quality RH services must be based on the needs of the affected populations, particularly the needs of women and girls. They must respect the religious and ethical values and cultural backgrounds of the communities, while conforming to universally recognized international human rights standards. ...

  • Human aromatase is responsible for estrogen biosynthesis and is implicated, in particular, in reproduction and estro-gen-dependent tumor proliferation. Themolecular structure model is largelyderived fromtheX-ray structure of bacterial cytochromes sharing only 15±20% identities with hP-450arom. In the present study, site directed mutagenesis experiments were performed to examine the role of K119, C124, I125, K130, E302, F320, D309, H475, D476, S470, I471 and I474 of aromatase in catalysis and for substrate binding....
