The importance of civil military relations assumes seminal importance in ensuring the success of all phases of a counter insurgency campaign. In the true tradition of the Clausewitzian dictum that war is the continuation of policy and vice versa; Pakistan Army has been employed as a matter of policy in counter insurgency operations in the erstwhile tribal areas. They have also been used in the stabilization operations to bring about normality in the insurgency ridden areas. In fact the employment of Pakistan Army in the stabilization process defies any previous example in any other country. In all phases of the conflict cycle, the military has worked hand in glove with its civilian counterparts. The civil-military coordination (CIMIC) in the insurgency ridden areas has taken place within the framework of the established ground rules of an organized counter insurgency campaign. It would not be unfair to say that the return to normality in the erstwhile FATA has only been possible because of a well-knit CIMIC architecture. This paper briefly explicates the salient points of the CIMIC aspect of the counter and post-insurgency part of the operations in the conflict zones and highlights the importance of this aspect of dealing with insurgencies.

The tropical regions have specific problems associated with high pathogenic density in the sewage sludge. The aim of this study was to select an adequate sludge stabilization and valorization system comparing the performance of four technologies: anaerobic stabilization without heating, aerobic stabilization, alkaline treatment with lime and aerobic composting. The study was performed in a pilot plant which was built and operated during six months. The main problem for the beneficial use of the sludge was its pathogenicity. All the systems allowed obtaining stabilized products which met the bacteriological criteria for some kind of use. The compost and the alkalinized sludge were bacteriologically safe for use without restrictions in accordance with the Mexican regulations. The accomplishment of the parasitological criteria for use was however impossible with the anaerobic and with the aerobic systems. The compost obtained at 55-60°C with 25d aeration time and the alkaline sludge fulfill the criteria established by for forest and agriculture use and for soil conditioning. The composting could reach the requirements for unrestricted use when operated at temperatures 65-70°C during 45 days which makes it the most adequate sludge treatment system for hot climate regions.

Rettery wastewaters were treated in anaerobic and aerobic ponds. Anaerobic treatment yielded efficiencies of BOD5 and COD removal as low as 20%. The treatment process conducted under aerobic conditions in aerated and stabilizing ponds arranged in series took from 18 to 20 days and gave efficiencies of BOD5 and COD removal amounting to 90%. The experimental results were interpreted by virtue of the Eckenfelder equation. Excess activated sludge was subjected to aerobic stabilization in a separate tank. A new technology was suggested for the existing obsolete industrial treatment plant.

This chapter shifts the focus to the third and final stabilization phase of the political communication cycle (PCC). During the stabilization phase, a new political communication order (PCO) takes shape through the building of norms, institutions, and regulations that serve to fix the newly established status quo in place. This status quo occurs when formerly innovative political communication activities become mundane, yet remain powerful. Much of the chapter details the pattern of communication regulation and institution construction over time. In particular, this chapter explores the instructive similarities and key differences between the regulation of radio and the internet, which offers important perspectives on the significance of our current place in the PCC and the consequences of choices that will be made over the next few years.
