Abstract:
This article describes relevant separation techniques for determining the removal of heavy metals from solutions and soils to achieve top quality in this field. Every innovation is quickly identified, regular working conditions are introduced and the innovation is implemented. The techniques described include the chemical precipitation (hydroxide, sulfide reagents or carbonate), coagulation / aggregation, ion exchange, extraction of chelators, soluble extraction, complex formation, electrochemical processes, cementation, includes film processing, evaporation, absorption and coagulation / fixation, glasses . Several narrative examples are given, focusing on ways to reduce waste and treat lead-contaminated soil. The article ends with a brief discussion of important screening requirements in this area.

Abstract:
Dysmenorrhea influences, women’s daily chores, restriction in social or functional activities, it affects their attendance in school and colleges. Many of them try to indulge in home remedies and analgesics without prescription. Throughout the world herbal medicines are used as an alternative treatment which is rising rapidly and it is universally accepted. Primary dysmenorrhea releases the excessive amount of prostaglandin in the blood. Carica papaya linn plant is also called as Paw-paw, belonging to family Caricaceae.

Abstract:
In 2007 Sri Lankan government introduced the National Policy of solid waste management and allocated LKR 5.7 billion in 2007 and LKR 44.24 billion in 2017 but the major waste management practice adopted by the Western Province even by the year 2020 is dumping to sanitary landfill without resource recovery. This practice contradicts to the 4-R principles advocated by the National Policy.

Abstract:
This paper was purposed to examine the comparison of the potential of coco fiber as a wall insulation of buildings in reducing heat based on the character. For the fulfillment of thermal comfort in buildings requires engineering, knowledge and skills and innovation. One way to reduce the hotter air inside the room can be done through the wall so as to reduce the use of air conditioning. The walls need protection and dampening of the suns heat that can make the room inside the building has thermal comfort. Based on this, it is necessary to conduct research on natural materials that can function in reducing heat through the wall of the building.

Abstract:
Over the past several years, there has been a decrease in rainfall, resulting in an increase in the water deficit in the forest area of Côte dIvoire. It is with the aim of looking for new areas suitable for the cultivation of oil palm that experiments have been conducted on the hydromorphic soils of La Mé and low-bottom divo. The objective of this study is to compare the productivity of oil palm grown on tertiary sands and in marshy areas.

Abstract:
Amorphous micron-sized particles were subjected to a quasi-static compression. A nanoindentation flat punch method has been developed to determine the contact pressure–strain behaviour of single micron-sized amorphous particle. Four groups of particles with same chemical compositions but different diameters were tested. Particle diameters varied from 3.36 µm to 10.05 µm. Three maximum strain levels of 20 %, 30 % and 40 % at constant deformation rate have been applied in the plastic regime. Existing contact mechanics models were discussed and applied to the elastic and plastic regime.

Abstract:
Afghanistan is an agrarian country and agriculture is the mainstay of national economy and rural livelihood. Majority of the farmers are engaged in subsistence farming and wheat is their main producing cereal crop. This study assessed the potential factors affecting low wheat productivity and large yield gaps in different production systems using a comparative stochastic frontier production function model. The study is documented on cross-sectional data of 235 randomly selected wheat growers in Ahmad Aba and Said Karam district of Paktia, Afghanistan.

Abstract:
It is always a major challenge for the disabled people to drive the car the especially four-wheeler. So, Being able to drive car is always grateful step for people with disabilities , but the conventional driving system installed in car it is not suitable for disabled driver to drive the vehicle. People with lower limbs disabilities cannot operate breaks, acceleration controls. Disabled people who are physically unfit always face some difficulty when it comes to driving. This paper presents the evolution of new driving system by using Arduino board and electromechanical actuator for a disabled driver. In this modification was made to exiting conventional system by using Arduino programming and hand operated Mechanisms for breaking and acceleration system.
