Abstract: Soil improvement using the geosynthetic layer technique is usually used for resolving many geotechnical problems. This technique provides a reinforced soil with high shear strength against erosion phenomenon that destroy foundations and lead to losses of human lives in Brazzaville City. The interest is certainly well displayed. Indeed, this work aims to experimentally assess the geosynthetics placement influence on the fine sand properties against water erosion phrnomenon. An experimental program has been carried for fine sand to study the soil shear strength from the soil not/and reinforced by geosynthetic layers. This made it possible to assess the soil displacements during the direct shear test. This opens the door to understand the geosynthetics effect in the soil for enhancing the soil shear strength for its possible use as a prevention method against soil erosion.

Key Words: Shear strength; geosynthetics; erosion; reinforcement; reinforced soil.

Abstract: Background: The Community Forestry Program (Hutan Kemasyarakatan/HKm) is a government program that does not merely provide an alternative so that communities around the forest can manage forests.The success of this community forestry activities is largely determined by the accuracy of planning, the readiness of community institutions, and the support of the Regional Government.. Materials and Methods: This study uses a qualitative phenomenological approach. The qualitative approach was chosen because the object of this research is a process of activity or action, namely community forestry management, and forest sustainability. The informants are members of the Community Forestry area management group, supporting NGOs, field assistants......

Abstract: Effect of Concentration of NASA POC and Various Organic Mulch on Growth and Yield of Purple Eggplant (Solanum melongena L.). The research location was carried out in Tapis Village, Tanah Grogot District, Paser Regency with a study period of 7 months from March 10 to September 03. The aim of this study was to determine the effect of giving NASA POC concentrations and various types of organic mulch using a two-factorial randomized block design which was repeated three times. The first factor is the treatment of various NASA POC concentrations consisting of 3 levels, namely p1 = (without NASA POC), p2 = (20cc/10 liters of water), p3 = (40cc/20 liters of water). The second factor was the treatment of various types of organic mulch which consisted of three levels, namely m1 = (without organic mulch), m2 = (alang-alang mulch), m3 = (rice straw mulch), the purpose of randomization......

Abstract: Background:The remediation of crude oil polluted sites in the Niger Delta has become a necessity owning to the increasing amount of crude oil spillage from both operational errors from oil companies, and those from vandalized crude oil pipes by illegal bunker activities. Crude oil polluted soils are characterized by the presence of Total Petroleum Hydrocarbon (TPH) and Chlorinated Hydrocarbons (VOC-Cl). The effect of these on plants and animals have been well studied. This study was done to determine the growth response or the performance of maize (Zea Mays) plant in a crude oil contaminated soil amended with leaf litters of Mangiferaindica. Materials and Methods. Top loamy soil collected from behind the Multipurpose Hall at the University of Port Harcourt, Nigeria was treated with different volumes of crude oil viz: 100ml, 200ml, and 400ml. 0.0ml, which represents no crude oil and served as control. In all......

Abstract: The information about the change of the sedimentary environment was recorded by the sediments. The southern coast of Laizhou Bay has experienced three transgressive and regressive events, forming a unique sedimentary environment since the late Pleistocene. This paper analyzes and discusses the evolution of the sedimentary environment based on the sediments in WB01 sedimentary columns. The strata of the study area have been characterized by land sea alternation. WB01 core can well divide 5 marine strata and 6 terrestrial strata. The marine strata and terrestrial strata show the characteristics of interphase distribution. The particle size of the sediment in the two deposition columns changes with the depth. Generally, the size of sediments in marine formations is smaller than that in continental formations.

Abstract: Studies attest to the fact that residential neighbourhood crime (RNC) which comes in the form of burglary, street incivility, robbery, graffiti and most times violent crime has been adjudged to have devastating consequences on the residents, immediate neighbourhood and government activities but not enough empirical works have been carried out to verify this. Hence, this study is set to quantitatively determine the veracity of the impact of residential neighbourhood crime on the residents, immediate neighbourhood and government activities using structural equation modeling (SEM). The results of the analyses reveal that RNC impacts significantly on the residents, immediate neighbourhood and........

Abstract: This research assesses the Environmental Management System (EMS) of International Oil Companies (IOCs) in Nigeria with emphasis to Shell using EMS yard sticks (such as oil spills and gas flares). It presents the level of EMS, problems and factors necessary for its success. An in-depth study on IOCs' environmental performance and operations was carried out by critically evaluating ISO 14001 standard and legislation to identify the environmental and organisational shortfalls. This was followed by examining the factors affecting the enforcement of legislation. Besides highlighting the shortfalls of complying with the Nigerian legislation and EMS standard, the study revealed.......
