It is the total sum of money allocated for the specific project for a specific period of time. The goal of the project budget is to cost control. The objective of this chapter is to give the implication of budgeting on contemporary project management. The main focus of this chapter is to discuss the introduction, history, agile approach, etc. It has a direct impact on the company's financial feasibility. The research would discuss the approaches for the projects budget estimation and various steps for cost control. There are two types of reserves against risks: one is the contingency reserve for identified risk, and the other is the management reserve for unidentified risks. The project manager needs to be aware of existing resources acquisition policies, guidelines, and procedures. The author discusses the procedures for project budgeting and methods for evaluation of project budgeting.

Glycaspis brimblecombei is an invasive insect pest of Eucalyptus that has spread rapidly around the world since its first report in California in 1998. The pest now occurs on at least four continents where Eucalyptus is grown as a non-native plantation species. To characterize global routes of invasion for this insect, we characterized the sequences of a portion of the Cytochrome Oxidase 1 (COI) gene from 105 individuals from the invasive and native range, including from Australia, Brazil, Chile, La Réunion, Mauritius, South Africa and the United States. In addition, we developed 13 polymorphic microsatellite markers, of which we used 11 to characterize the diversity in the same 105 specimens. Our results suggest that there have been two independent introduction events from Australia, which is assumed to be the origin, to distinct parts of the adventive range. The first introduction was into the United States, from where it appears to have spread to South America and eventually to South Africa. This finding highlights the threat of bridgehead populations to accelerate pest invasions in Eucalyptus, even if those populations are on widespread non-commercial populations of Eucalyptus (as in California). A second introduction appears to have occurred on the islands of Mauritius and La Réunion and provides another example of the establishment of independent lineages of invasive global insect pests. This complex invasion pattern mirrors that found in other Eucalyptus pests.

Genomic analysis can be a valuable tool to assistmanagement of non-native invasive species, through determining source and number of introductions as well as clarifying phylogenetic relationships. Here, we used whole chloroplast sequencing to investigate the introduction history of Passiflora foetida sensu lato in Australia and clarify its relationship with other Passiflora species present. Phylogenetic analysis of chloroplast genome data identified three separate genetic lineages of P. foetida s. l. present in Australia, indicating multiple introductions. These lineages had affinities to samples from three separate areas within the native range in Central and South America that represented phylogenetically distinct lineages. These results provide a basis for a targeted search of the native range of P. foetida s. l. for candidate biological control agents that have co-evolved with this species and are thus better adapted to the lineages that are present in Australia. Results also indicated that the Passiflora species native to Australia are in a separate clade to that of P. foetida s. l. and other introduced Passiflora species cultivated in Australia. This knowledge is important to assess the likelihood of finding biological control agents for P. foetida s. l. that will be sufficiently host-specific for introduction in Australia. As P. foetida s. l. is a widespread non-native invasive species across many regions of the world, outcomes from this work highlight the importance of first evaluating the specific entities present in a country before the initiation of a biological control program.

Gene therapy is used to correct defective genes in order to cure a disease or help your body better fight disease. Gene therapy is the introduction, removal or change in genetic material specifically DNA or RNA into the cells of a patient to treat a specific disease. Disease is caused to mutation. Genes influence all from the color of our hair to immune system, but genes are not built correctly. Targets of the gene therapy causing diseases. Gene therapy uses section of DNACurrently gene therapy is being tested only for disease that have no. other cures. Interest area of this review covers introduction, history, DNA transfer, Types of gene therapy, working of therapy, techniques, Delivery system, strategies, technique challenges, risks, gene introduction site and clinical applications of gene therapy.
