Research ArticleOpen accessIn the abstractNano-Diamond Hybrid Materials for Structural Biomedical ApplicationRaffaella Aversa, Relly Victoria V. Petrescu, Antonio Apicella, Florian Ion T. PetrescuThe development of new diamond based bio-mechanically active hybrid nano-structured scaffolds for cartilage cells tissue engineering are proposed in this study. Innovative tissue engineering biomimetic materials based on hydrogel have shown attractive physical, biological and mechanical properties in several biomedical applications. A highly biocompatible novel hybrid material based on nanodiamonds and hydrophilic poly-(hydroxyl-ethyl-methacrylate) (pHEMA) is proposed. The aim of this … …American Journal of Biochemistry and Biotechnology, Vol. 13, Issue 1 · 9 Mar 2017 · 9,189 accessesView PDFCite
Literature ReviewOpen accessIn the abstractOn Destructive Peri-implant Bone LossAndre J. ViljoenDestructive peri-implant bone loss is distressing for both the patient and the treating dentist(s). In severe cases peri-implant bone loss may cause jawbone mutilation, making re-treatment highly complex or impossible and violating the treatment philosophy of “first, do no harm”. There are a multitude of causes of bone loss around a dental implant. These include, but are not limited to, … …Current Research in Dentistry, Vol. 10, Issue 1 · 25 Nov 2019 · 7,475 accessesView PDFCite
Research ArticleOpen accessIn the abstractPhytoremedial Potential of Tagetes Erecta Under Mycorrhizal Inoculation in Heavy Metal Polluted SoilI.O. Aina, F.L. Amusa, A.D. Olasupo et al.Investigation of the growth of Tagetes erecta under different levels of contamination of Copper (Cu) and Lead (Pb) in the soil and effects of mycorrhizal species (Glomus mosseae) on Cu and Pb to identify hyperaccumulator plants in tropical environment that could be used in remediation of heavy metal from contaminated soils. It was a greenhouse experiment consisted of factorial combination … …American Journal of Environmental Sciences, Vol. 15, Issue 5 · 28 Oct 2019 · 7,475 accessesView PDFCite
Research ArticleOpen accessIn the abstractProposed Soil Quality Index for Rehabilitated Tropical Forest Sites in MalaysiaDaljit Singh Karam, Arifin Abdu, Keeren Sundara Rajoo et al.A proposed soil quality index named Tropical Soil Quality Index 2 (TSQI2) was developed in this study using statistical analysed data of selected properties (physical, chemical and biological) of composite soil samples collected from natural, secondary and rehabilitated forests of Chikus and Tapah Hill Forest Reserves, Perak, Malaysia. Results of soil evaluation using TSQI2 showed higher values for planted forest … …American Journal of Applied Sciences, Vol. 14, Issue 1 · 30 Dec 2016 · 8,156 accessesView PDFCite
Research ArticleOpen accessIn the abstractThermodynamic Model of Calcium Carbonate System of Soil SolutionAbdulmalik A. Batukaev, Anatoliy P. Endovitsky, Andrey G. Andreev et al.Carbonate system determines the basic processes of soil formation and evolution. The aim of research was to show the importance of chemical Carbonate Calcium Equilibrium (CCE) in soil solutions. CCE causes a degree of soil solution’s saturation with CaCO3 as a factor of carbonate geochemical cycle. CCE depends on chemical composition, pH, Eh, buffering properties of liquid phase, dissolution, migration, … …American Journal of Agricultural and Biological Sciences, Vol. 11, Issue 2 · 18 May 2016 · 7,981 accessesView PDFCite
Research ArticleOpen accessIn the abstractInvestigation of the Fatty Acid Profile in Some Macroalgae in Relation to the Environmental Conditions for Biodiesel ProductionNayrah Abdel Naby Shaltout, Nihal Galal Shams El-DinIn this study, fatty acids profile was determined in four algal species; namely Ulva fasciata (Chlorophyta), Corallina mediterranea, Corallina officinalis and Pterocladiella capillacea (Rhodophyta) which were collected from two sites (Abu-Qir Bay and Eastern Harbor) located on the Egyptian Mediterranean Sea during the four seasons in the period (2011-2012). In addition, nutrient content in the algal species (total nitrogen and … …American Journal of Environmental Sciences, Vol. 11, Issue 6 · 14 Dec 2015 · 7,338 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 · 7,280 accessesView PDFCite
Research ArticleOpen accessIn the abstractAdsorption of Nickel and Zinc by Residual SoilsNur ’Aishah Zarime, W. Y. Wan Zuhairi, Sivarama KrishnaSoil has long been utilized as low cost liner material to prevent contamination from leachate to groundwater media. To find a suitable soil material for this purpose is a great challenge. This study describes the potential use of residual soil to functions as engineered clay liner for waste disposal landfill in Malaysia. Three types of residual soils were investigated namely … …American Journal of Environmental Sciences, Vol. 10, Issue 6 · 5 Dec 2014 · 7,122 accessesView PDFCite
Research ArticleOpen accessIn the abstractINCREASING ADSORPTION OF ACTIVATED CARBON FROM PALM OIL SHELL FOR ADSORB H2S FROM BIOGAS PRODUCTION BY IMPREGNATIONWasan Phooratsamee, Kanokorn Hussaro, Sombat Teekasap, Jongjit HirunlabhBiogas is the combustible gas produced through a biological process, known as anaerobic digestion which is the process operated at low-temperature and without air. Biogas consists of 55-80% CH4, 20-45% CO2 with trace amount of H2S and other impurities. Common H2S removal technologies from biogas fall into one of adsorption on a solid such as iron oxide based materials, activated … …American Journal of Environmental Sciences, Vol. 10, Issue 5 · 16 Aug 2014 · 7,677 accessesView PDFCite
Research ArticleOpen accessIn the abstractCHARACTERIZATION OF OIL PALM EMPTY FRUIT BUNCH AND RICE HUSK BIOCHARS AND THEIR POTENTIAL TO ADSORB ARSENIC AND CADMIUMNorazlina Abu Sari, Che Fauziah Ishak, Rosenani Abu BakarBiochar as a new soil amendment has a potential in controlling the fate of trace elements in the soil system. However, the production of biochar from different feedstocks and pyrolysis conditions resulted in variable biochar properties which have an influence on trace elements availability. The experimental works are focused on physical and chemical properties of biochars produced from Empty Fruit … …American Journal of Agricultural and Biological Sciences, Vol. 9, Issue 3 · 13 Aug 2014 · 10,590 accessesView PDFCite
