Research ArticleOpen accessIn the abstractUnder WaterRaffaella Aversa, Relly Victoria Petrescu, Antonio Apicella, Florian Ion Tiberiu PetrescuWith a 361 million square Km surface and a volume of 1370 million of cubic kilo, world seas and oceans have represented and still remain the privileged space for living species evolution. Other than being the 70% of the Earth surface, water environment, contrary to the terrestrial one where life essentially develops in 2 dimensions, is a 3D fully volume … …OnLine Journal of Biological Sciences, Vol. 17, Issue 2 · 10 Jun 2017 · 7,231 accessesView PDFCite
Research ArticleOpen accessIn the abstractUnderstanding Hybrid Additive Manufacturing of Functional DevicesSantosh Kumar Parupelli, Salil DesaiThe fabrication of electronic components in three-dimensional space is critical for building multifunctional devices. Traditional manufacturing approaches are limited to building planar device configurations. In order to address this limitation, our group has developed a novel hybrid additive manufacturing process that can deposit multi-material patterns on conformal substrates. This direct-write approach involves the combination of microextrusion, pico jet and laser … …American Journal of Engineering and Applied Sciences, Vol. 10, Issue 1 · 20 Mar 2017 · 8,154 accessesView PDFCite
Research ArticleOpen accessIn the abstractHeavy Metals Content of the Grassland Soil around Katima Mulilo Municipal Solid Wastes Dumpsite, NamibiaJ. Abah, P. Mashebe, S.A. OnjefuThe effects of open wastes dumpsites on the immediate vicinity continue to generate safety concern. This study determined the levels of lead, chromium, cadmium, arsenic, nickel, cobalt, copper and manganese in soil samples collected at two depths: 0-15 and 15-30 cm within and around Katima Mulilo municipal solid wastes dumpsite and a control site. The samples were digested according to … …American Journal of Environmental Sciences, Vol. 13, Issue 2 · 18 Mar 2017 · 7,481 accessesView PDFCite
Research ArticleOpen accessIn the abstractSequence Stratigraphic Analysis from Well Logs of an X-Field, Niger Delta, NigeriaGodwin Omokenu Emujakporue, Alphonsus Joseph EyoThe sequence stratigraphic analysis of the area was studied using well log information in order to determine the lithostratigraphy, chronostratigraphy, possible reservoir sands, age and depositional environment of the study area for opportunities that will support exploration program. The depositional environment penetrated by the wells interpreted from log signatures gave three major facies association. The blocky and coarsening upward (funnel … …Current Research in Geoscience, Vol. 6, Issue 2 · 11 Jul 2016 · 13,975 accessesView PDFCite
Research ArticleOpen accessIn the abstractConformal Mapping of Temperature Variation in Compost HeapJonah Chukwuemeka Agunwamba, Oji Achuka NwokeLaboratory in vessel trapezoidal compost system was designed and constructed. Temperature variation in the compost heap was measured for five days at various depths. Mathematical model for the variation of temperature of the composting process was developed using Conformal Mapping Technique. One of the parameters in the model had two distinct roots, one a positive root and the other negative … …American Journal of Environmental Sciences, Vol. 12, Issue 3 · 17 Jun 2016 · 7,347 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Fertility Status of Soils at Rehabilitated Degraded Land in Universiti Putra Malaysia Planted with Pinus caribaea and Swietenia macrophyllaMohammad Nazrin Abdul Malik, Arifin Abdu, Daljit Singh Karam et al.Soil fertility (both physical and chemical) is one of the important factors limiting plant growth. So, the fertility of the soils should be determined before growing crops and after the establishment of forest rehabilitation. A study was conducted to determine the fertility status of soils at rehabilitated degraded land in Universiti Putra Malaysia. The main objective was to compare the … …American Journal of Applied Sciences, Vol. 12, Issue 10 · 5 Nov 2015 · 7,276 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Criterion for Determining the Ultimate Pullout Capacity of Plate Anchors in Clay by Numerical AnalysisHaixiao Liu, Fangmei Su, Zhou LiThe Ultimate Pullout Capacity (UPC) is an important index in designing and analyzing plate anchors. However, there are still uncertainties in determining the UPC through the load-displacement curves calculated from numerical analysis. The review on the existing criteria for determining the UPC also demonstrates that there has not been a generally accepted criterion and most existing criteria are not only … …American Journal of Engineering and Applied Sciences, Vol. 7, Issue 4 · 19 Jan 2015 · 8,413 accessesView PDFCite
Research ArticleOpen accessIn the abstractStatus of Soil Microbial Population, Enzymatic Activity and Biomass of Selected Natural, Secondary and Rehabilitated ForestsK. S. Daljit Singh, A. Arifin, O. Radziah et al.Substantial clearance of forests and conversion of forest into various land use types contribute to deterioration of soil fertility and associated nutrients loss. Soils from natural and rehabilitated forest in Chikus Forest Reserve and also enrichment planting forest and secondary forest of Tapah Hill Forest Reserve, Perak, Malaysia were selected in order to assess the influence of land use change … …American Journal of Environmental Sciences, Vol. 9, Issue 4 · 28 Aug 2013 · 7,803 accessesView PDFCite
Research ArticleOpen accessIn the abstractCommunity Structure and Abundance of Tintinnids in the Bay of Bengal During the SpringHuaxue Liu, Liangmin Huang, Zhixin Ke et al.The Bay of Bengal (BoB) locates in eastern part of the northern Indian Ocean, with a unique inter-related oceanographic system due to the monsoon and enormous runoffs’ supply. microbial food web often dominated the stratified Tropical Ocean, while few studies have been taken up to the tintinnids ciliates. Community structure and abundance of tintinnids were investigated in transact 10° N … …American Journal of Agricultural and Biological Sciences, Vol. 7, Issue 4 · 20 Sep 2012 · 7,898 accessesView PDFCite
Research ArticleOpen accessIn the abstractVariability of Hydraulic Conductivity Due to Multiple FactorsSanjit K. Deb, Manoj K. ShuklaSoil properties are greatly influenced by intrinsic factors of soil formation as well as extrinsic factors associated with land use and management and vary both in time and space. Intrinsic variability is caused by the pedogenesis and usually takes place at large time scales. The variability caused by extrinsic factors could take effect relatively quickly and could not be treated … …American Journal of Environmental Sciences, Vol. 8, Issue 5 · 13 Aug 2012 · 10,219 accessesView PDFCite
