Palm oil is dark yellow to red with a sweet taste and violet scent. Under the action of oxygen in the air, palm oil discolors due to the oxidation of carotene. The sample at different temperatures was recorded at different shear rates. Based on the rheograms (graph of the average shear stress versus shear rate), the studied ones proved to be Newtonian fluid. The shear range used did not significantly affect the absolute viscosities of the palm oil at different temperatures. The absolute viscosities of palm oil have decreased with increasing temperature and can be equipped with an Arrhenius-type relationship.

Significant progress has been made on biopolymers in recent years. Biopolymers are preferred to other materials because they have specific physical, chemical, biological, biomechanical, and degradation properties. Many natural or synthetic biopolymers can degrade hydrolytically or enzymatically and are used for many applications.

Bioremediation includes processes such as bioventing, bioaugmentation, phytoremediation, biopiles, and composting. In this chapter, we details the characteristics, utilization and operating conditions of each process. Bioremediation is understood, according to the general definition, as the use of living organisms (microorganisms, plants, etc.) to improve and restore the ecological condition of a polluted or degraded substrate (area, land, aquifer, etc.) to better, favorable quality parameters life, harmless, non-polluting or to return it to its previous state. Soil treatment technologies through bioremediation include two types of treatments: in situ biological treatments (bioventilation, bioaugmentation, phytoremediation in soil) and ex situ biological treatments of polluted soils (biopiles and soil cultivation).

This chapter includes the main characteristics and rheological and thixotropic properties of drilling fluids. The drilling fluid is composed of a liquid phase and a solid phase. The rheological properties characterize the flow behavior of the drilling fluids, including the resistance to displacement of some bodies in the fluid mass. These properties allow to evaluate the pressure and pumping energy of the drilling fluids, the washing conditions as well as the evacuation of the detritus, the danger of erosion of the walls. To describe the behavior of rheological fluids, we use the Bingham and Ostwald de Waele models.

The main goal of vegetable growers is to obtain early and quality harvests. In this article, the experiments were carried out in the period 2005–2007, and the culture behavior of new early cabbage hybrids, the influence of plant thickness on the production of cabbage grown in greenhouses and the field and the influence of additional protection were investigated on the early production of cabbage in greenhouses and in the field. During the years 2005–2007, studies were undertaken on the culture behavior of six hybrids and an early cabbage variety, using two different planting plots and two protection systems.

Ecological agriculture promotes sustainable, diversified and balanced production systems, in order to prevent crop and environmental pollution. Ecological production in plant culture, without the use of harmful traditional products, has been a special concern for several decades in economically developed countries. Interest in ecological products and production is continuously growing in our country as well. Leguminous plants play a particularly important role in ecological agriculture. The favorable effect of legumes for successor plants has been known since ancient times. This article includes the importance and biological characteristics of legumes.
