This study was carried out on the site of oil palm agro-industrial exploitation in South-East Gabon. The aim was to evaluate effectiveness of three herbicides: Roundup (glyphosate), Finish (c) and Ally (metsulfuron methyl) on the weed flora. An inventory weed flora was conducted to estimate abundance-dominance, post-treatment patch coverage, weed recurrence time, and the optimal herbicide application rate. The results obtained show that the weed flora is composed of 22 dominant species, divided into 20 genera and 15 families. The three predominance families are Rubiaceae, Poaceae and Cyperaceae. A mixture of two herbicides, specifically Finish Ally (glyphosate-metsulfuron methyl and metsulfuron methyl), is the most effective, with 85% of weeds eliminated by day 30 and 74 days of recurrence.

We know that a chassis to an automobile is like a skeleton to a body. Chassis stiffness is what separates a great car to drive from what is merely Ok. Every chassis is a compromise between weight, component size, complexity, vehicle intent and ultimate cost. And even with a basic design method, strength and stiffness can vary significantly, depending on the details. This paper lists some techniques which could be used to further strengthen the chassis of a car. A stiff and rigid chassis ensures enhanced controlling of the vehicle along with imparting higher safety and comfort levels to the occupants.

This paper reviews the PLC applications in the industry of cutting machines. This paper also reviews the PLC properties, different types of hacksaw used for cutting purposes. Today, there is lot of advancements in these fields as every industry is getting automated. For cutting materials for mass production conveyor systems are widely used. There are two types of conveyor: Belt type and Roller type. Feed of cutting materials is also done with the help of conveyor. Pneumatic System is used for smooth operation of hacksaw.

Plastics find the major application in automobile components and the interiors and exterior furnishings. There are many applications of plastics in automobile ranging from power trains, under the hood and chassis. Polypropylene (PP) is been widely used in the automobile sector in recent years. Polyurethane (PU), acrylonitrile butadiene styrene (ABS), polyvinyl chloride (PVC), and polyethylene (PE) are the major plastics used that have been great demand in automobile engineering. But after certain period these plastics begin the degradation process, thus the use of the reinforced plastic is been on the large scale. These reinforced plastics are degradable in nature. Its high time need to test the reinforced plastic under impact load and energy levels.
