The large genus Orthomorpha is rediagnosed and is shown to currently comprise 51 identifiable species ranging from northern Myanmar and Thailand in the Northwest to Lombok Island, Indonesia in the Southeast.Of them, 20 species have been revised and/or abundantly illustrated, based on a restudy of mostly type material; further 12 species are describ

Summary: Biological nitrogen fixation catalyzed by nitrogenase contributes greatly to the global nitrogen cycle.Nitrogenase expression is subject to regulation in response to nitrogen availability.However, the mechanism through which the transcriptional activator NifA regulates nitrogenase expression by interacting with PII nitrogen regulatory prot

Abstract Background Associations between animal species require that at least one of silbrade the species recognizes its partner.Parabioses are associations of two ant species which co-inhabit the same nest.Ants usually possess an elaborate nestmate recognition system, which is based on cuticular hydrocarbons and allows them to distinguish nestmate

Transportation activities are stages in the product distribution system.The purpose of the transport system is to minimize the total cost.If there is more than one objective function and consider more than one type of vehicle, uunipelti it is called a multiobjective solid transportation problem.In some cases, the parameter transportation model is u

BACKGROUND:Resistance emergence against antileishmanial drugs, particularly Sodium Antimony Gluconate (SAG) has severely hampered the therapeutic strategy against visceral leishmaniasis, the mechanism of resistance being indistinguishable.Cysteine leucine rich protein (CLrP), was recognized as one of the overexpressed proteins in resistant isolates
