The aim of this study was to improve the strength black cotton soil for its suitability road subgrade construction using wastes from plastic bottles and glass waste powders. Currently, nondecomposable glasses have become threats human health environment. This used replace cement, since cost cement raised due energy raw material use as stabilizer in weak soil. powder (WGP) chips were mixed with ...

Tanah merupakan tempat untuk suatu bangunan atau struktur didirikan baik berbentuk maupun jalan. Daya dukung dari tanah sangat berpengaruh pada perlakuan terhadap yang akan dibangun diatasnya. Berdasarkan tes Dynamic Cone Penetration Kondisi jalan Kampung Juhut Kecamatan Karangtanjung Kabupaten Pandeglang memiliki nilai California Bearing Ratio sebesar 3,1% ini masih dibawah standard dasar perk...

Recently, geotechnical studies have been conducted more progressively to utilize dredged soil. The inclusion of shredded rubber (SR) and natural minerals (NM) stabilize soil (DS) has become an exciting issue in the field. This technique can be a promising environmental innovation for future. study aimed investigate unconfined compressive strength (UCS), California bearing ratio (CBR), embankmen...

The soils which show very high shear strength in a dry state but rapidly lose their on wetting are known as collapsible soils. Such rapid and massive loss of produces severe distress leading to extensive cracking differential settlements, instability building foundations, even collapse structures built these Waste marble dust is an industrial byproduct being produced large quantities globally p...

Soil characteristics and methanogenesis were investigated in Fluvisols of the Balandra lagoon mangrove in Baja California, Mexico in March/April 1995. The grain size distribution was dominated by the silt fraction (54-92%), sand and clay contents were 6-44% and 0-19%, respectively. Bulk density was 0.6-1.5 g cm, the water content 290-690 ml 1 and the air content 38-200 ml 1. The soils always sh...

it is very important to determine the stable nitrogen isotope ratio for the nitrogenous substances in aerosols and the geochemistry behavior of stable nitrate ion isotopes in aerosols in order to elucidate the chemical and physical functions of clouds. hence, aerosol field sampling was conducted in the skies offshore from malibu beach and santa barbara, california, u.s.a. on 16 and 18 july 2009...

The Guerrero Negro (GN) hypersaline microbial mats have become one focus for biogeochemical studies of stratified ecosystems. The GN mats are found beneath several of a series of ponds of increasing salinity that make up a solar saltern fed from Pacific Ocean water pumped from the Laguna Ojo de Liebre near GN, Baja California Sur, Mexico. Molecular surveys of the laminated photosynthetic microb...

OBJECTIVE To examine acute energy costs of multi-modal activity-based therapy (ABT) in men and women with spinal cord injury (SCI). STUDY DESIGN Descriptive case series. SETTING An outpatient center in California. PARTICIPANTS Seven men and women (age = 28.3 ± 11.6 years; duration of injury = 4.3 ± 2.5 years) with injury levels ranging from C5 to T8. INTERVENTION Activity-based therapy....

Background Gun shows are an important source of firearms, but no adequately powered studies have examined whether they are associated with increases in firearm injuries. Objective To determine whether gun shows are associated with short-term increases in local firearm injuries and whether this association differs by the state in which the gun show is held. Design Quasi-experimental. Setti...
