Infrastructure facilities in many countries have been repeatedly subjected to natural or human-induced disasters. International aid institutions, such as the United Nations Development Program （UNDP）, United States Aid International Development （USAID）, Japan International cooperation Agency （JIcA） and the world Bank International Aid Development （IDA）, are endeavoring to assist in the reconstruction of devastated countries. Development institutions normally face the problem of selecting and implementing relevant priority infrastructure projects that are needed in various sectors. Usually there are also several key local players in the decision making process. In many cases, these main decision makers have contradictory objectives that lead to conflict and thereby hamper the reconstruction process. In response to this kind of problem, an effective approach has been developed within the field of Multiple criteria Decision Analysis （McDA）, the Analytical Hierarchy Process （AHP）, that can assist decision makers in prioritizing projects to meet specified goals and objectives. Using the AHP approach, the problem of selecting infrastructure projects is dealt with systematically when applying this flexible McDA technique. This approach takes into account possible uncertainties and social discrepancies, and can use the judgments of the decision makers themselves when there is a lack of technical or historical data. Decision makers from international financial aid institutions, donor agencies, governmental and the local community can utilize this proposed approach.

Barbed surgical sutures have attracted worldwide attention in recent years. The plurality of barbs projecting out and penetrating into surrounding tissue eliminates the need for tying a knot. In the current study,nylon and polypropylene( PP) barbed sutures with two different barb geometries designed to anchor in porcine skin and tendon tissues were fabricated by a specially designed mechanical cutting machine. The tensile properties were compared between the barbed and unbarbed control sutures. The in vitro tissue anchoring ability was measured by two tissue /suture pullout tests,one for skin and the other for tendon tissue. Regardless of the type of tissue,the PP barbed suture with its higher modulus had a superior anchoring ability. Given the same suture material,improved anchoring performance was shown in tendon tissue.

Batesian mimics are harmless prey species that resemble dangerous ones （models）, and thus receive protection from predators. How such adaptive resemblances evolve is a classical problem in evolutionary biology. Mimicry is typically thought to be difficult to evolve, especially if the model and mimic produce the convergent phenotype through different proximate mecha- nisms. However, mimicry may evolve more readily if mimic and model share similar pathways for producing the convergent phenotype. In such cases, these pathways can be co-opted in ancestral mimic populations to produce high-fidelity mimicry with- out the need for major evolutionary innovations. Here, we show that a Batesian mimic, the scarlet kingsnake Larnpropeltis elap-soides, produces its coloration using the same physiological mechanisms as does its model, the eastern coral snake Micrurus fulvius. Therefore, precise color mimicry may have been able to evolve easily in this system. Generally, we know relatively little about the proximate mechanisms underlying mimicry .

we reinvestigate the collective effects of the retardation as well as the bending on the coulomb excitation cross sections and also on the B（E2） strengths of some neutron-rich isotopes using the intermediate energy coulomb excitation theory. It is found that the B（E2） strengths extracted from the experimental coulomb excitation cross section data get suppressed approximately by 6%. Furthermore, the obtained B（E2） strengths in the energy range 30-100 MeV/A are found to be in better agreement with the corresponding values known from other sources, than those obtained by using the recoil-corrected relativistic coulomb excitation theory.
