Based on the idea of the special function transform method we associate a connection between solutions of nonlinear evolution equations of higher-order and a predestinated nonlinear ordinary differential equation. Here, in this connection we use the Abel Equation for the first time. The solution manifold of Abel’s equation stated in a most general form allows one to determine unknown analytical classes of solutions of any evolution equations.

By considering the Burgers Equation acting a test example new rational-type of solutions result. Nevertheless it should be emphasised that the solution procedure of complicate nonlinear ordinary differential equations as in the case of similarity reduction techniques is obviated. The unknown solution function of the nonlinear partial differential equation under consideration is assumed to be comprised in additional form as both a linear and a reciprocal part. This auxiliary function is also a solution of Abel’s Equation.

Under weak conditions, Josephson's state dependent impulsive equation with Henstock-Kurzweil integrable forcing is shown to admit an absolutley continuous antiperiodic generalized solution with Lebesgue integrable first derivative and Hanstock-Kurzweil integrable second derivative.  A uniqueness condition is also given.

A number of rows of inline configuration serrated fin heat exchanger were modeled using CFD to examine a number of characteristics previously explored in the special single row case.  The development of heat transfer in the bundle is discussed, paying particular attention to the special effects generated by the serrations and their influence on the heat transfer over the full fin surface. A comparison between a commercial pressure drop prediction method and the CFD results is then presented and a discussion of the difference in results given. A direction for a pressure drop prediction method for serrated finned tube bundles is also outlined from the results.

Transfer of documents and information in various establishments are usually characterized with various problems such as loss of documents, delay of documents   delivery   and   some   bureaucratic   problems that are non-productive to the establishment. Overcoming   these   problems   calls   for   an   automated software  known  as  workflow  application software  that promises   reliability,   timeliness   and   precision   in   the treatment  of  documents  in  any  establishment. In this work, a  workflow engine for acquisition and management  of  vehicle  fleet  of  Guinness  Nigeria  PLC was  design  to  overcome  the  bottleneck  associated  with this  process.  The workflow engine is C# based with ASP.NET.   C#   is   the   host   application   which   is   time efficient and web enabling. The workflow  engine design is  capable  of  handling  car  requisition  and  allocation  to various cadres of employee in the establishment through document  transfer.  The advantage of this work is in its reliability,    efficiency and flexibility of document management. We also propose this work as open source workflow application with customization    to any organization needing it.

Artificial groundwater recharge is a process by which the groundwater reservoir is augmented at a rate exceeding the augmentation rate under natural conditions of replenishment. In some parts of India, due to over-exploitation of groundwater, decline in groundwater levels resulting in shortage of supply of water, and intrusion of saline water in coastal areas have been observed. In such areas, there is need for artificial recharge of groundwater by augmenting the natural infiltration of precipitation or surface-water into underground formations by methods such as water spreading, recharge through pits, shafts, wells et cetera The choice of a particular method is governed by local topographical, geological and soil conditions; the quantity and quality of water available for recharge; and the technological-economical viability and social acceptability of such schemes. This paper discusses various issues involved in the artificial recharge of groundwater.
