Construction of flexible pavements with hot mix asphalt (HMA) mixtures consumes huge energy which impacts the resources and the environment of the world. Warm Mix Asphalt (WMA) is an effective alternative as they produced with lower mixing and compaction temperature than those used in HMA production. This technology decreases energy consumption, saves money, and reducing the environmental pollu...

The increase in the number of road construction projects has led to an need for pavement materials (aggregate and asphalt). Currently it takes about 1.6 million tonnes/year asphalt, as well aggregate. Seeing these conditions, is necessary anticipate use waste or natural resources that have not been utilized optimally. In this study, fly ash (PLTU waste) was used aggregate Asbuton (Buton Island ...

We present a model of a dynamic and complex economy in which the creation and the destruction of money result from interactions between multiple and heterogeneous agents. In the baseline scenario, we observe the stabilization of the income distribution between wages and profits. We then alter the model by increasing the flexibility of wages. This change leads to the formation of a deflationary ...

Many studies have estimated the aggregate import demand function for Pakistan by using non-stationary data. Their findings suffer from the so-called ‘spurious regression’ problem. This study attempts to estimate the aggregate import demand function for Pakistan by employing Johansen and Juselius cointegration technique on the annual data for the period 1975-2005. Our results show that there is ...

The paper offers a preliminary hypothesis of how the global system is controlled. Loosely interacting centers of control, together with less well-defined forces, control global social activity. Centers of control include government, international organizations, and informal networks. These forces have maintained relative social stability. However, population and aggregate global consumption are...

The stability of proteins is a subject of intense current interest. Aggregation, as a dominant degradation pathway for therapeutic proteins, may cause multiple adverse effects, including loss of efficacy and immunogenicity. In the present study, the formation of aggregates in lenograstim under physiological conditions was monitored. For this purpose, a simple and selective size-exclusion high-p...

Recycled aggregate pavement in bituminous can be repercussion to mitigation the exhaustion of rudimentary and asphalt, orientation alleviation quantities tailings organized into garbage dumps. This research aimed investigate performance Hot Mix Asphalt (HMA) surface with recycled concrete (RCA) as a replacement natural aggregates (NA) four substitution rates (0, 20, 40, 60) % from coarse aggreg...
