Research ArticleOpen accessIn the abstractEffects of Stripping Frequency on Semen Quality of Endangered Caspian Brown Trout, Salmo trutta caspiusSaeed Hajirezaee, Bagher Mojazi Amiri, Ali Reza MirvaghefiProblem statement: Because of dramatic declines in stocks of endangered Caspian brown trout males, Salmo trutta caspius in Caspian Sea, each male brooder is stripped indispensably more than once during the spawning season in other to artificial insemination in hatchery. The aim of the present study was to assay the changes of indicators of semen quality (sperm motility, sperm production, … …American Journal of Animal and Veterinary Sciences, Vol. 4, Issue 3 · 30 Sep 2009 · 7,480 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffect of Precipitation Fluctuation on Soil Carbon Storage of a Tropical Peat Swamp ForestAnton Eko Satrio, Seca Gandaseca, Osumanu Haruna Ahmed, Nik Muhamad Ab. MajidProblem statement: It is important to compare the effect of extremely different rainfall conditions on soil carbon storage of lowland tropical peat swamp forest. Therefore, under these natural rainfall gradient, the objectives of this study were to determine whether rainfall affects soil carbon storage of a tropical peat swamp forest and to determine what correlations between variables occurs which stimulate … …American Journal of Applied Sciences, Vol. 6, Issue 8 · 31 Aug 2009 · 8,606 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Shuffle Image-Encryption AlgorithmA. A. Yahya, A. M. AbdallaProblem statement: Image encryption needs to be secure by resisting statistical attacks and other types of attacks. Approach: The new algorithm, call it the Shuffle Encryption Algorithm (SEA), applies nonlinear s-box byte substitution. Then, it performed a shuffling operation partially dependent on the input data and uses the given key. Results: SEA was implemented and tested with different data, mainly … …Journal of Computer Science, Vol. 4, Issue 12 · 31 Jul 2009 · 8,359 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffects of Tillage Methods on Soil Fragmentation in Loamy-Clay SoilsYousef Abbaspour-Gilandeh, Vali Rasooli Sharabiani, Ahmad KhalilianProblem statement: Soil fragmentation is a primary aim in tillage in order to create a favorable soil environment for crop growth. Soil fragmentation is defined as the process of breakdown and crumbling of soil aggregates. Currently, there is no published research data on optimum tillage operations for seedbed preparation in loamy-clay soils of western Caspian Sea region of Iran. Approach: … …American Journal of Agricultural and Biological Sciences, Vol. 4, Issue 2 · 30 Jun 2009 · 10,247 accessesView PDFCite
Research ArticleOpen accessIn the abstractLiquefaction Susceptibility in the Northern Provinces of ThailandSupot Teachavorasinskun, Pichai Pattararattanakul, Pulpong PongvithayapranuProblem statement: There are quite a few active faults recently found in the western and northern parts of Thailand, which could possibly induce earthquakes of magnitude (ML) of 5.5-6.5. Although seismic design code has been enforced in the area since 1980, the fundamental knowledge on dynamic soil behavior has not been extensively attained. Approach: Collection of existing borehole information in … …American Journal of Engineering and Applied Sciences, Vol. 2, Issue 1 · 31 Mar 2009 · 8,337 accessesView PDFCite
Research ArticleOpen accessIn the abstractOrganochlorine Pesticide Residues in Fish Samples from Lagos Lagoon, NigeriaDavid Adeyemi, Grace Ukpo, Chimezie Anyakora, JohnPaul UnyimaduThe organochlorine pesticide (OCPs) residues were measured in three species of fish Tilapia zilli (Red belly Tilapia), Ethmalosa fimbriata (Bonga Shad) and Chrysichthys nigrodigitatus (Catfish). These fish species are a significant part of the diet of residents of Lagos Nigeria. The organochlorine pesticides analyzed include DDT(pp'1,1,1-trichloro-2,2-bis-(4-chlorophenyl) ethane), DDD, DDE (pp 1,1-dichloro-2, 2-bis-(4-chlorophenyl) ethylene, HCH (gamma 1,2,3,4,5,6-hexachlorocylohexane, HCB (hexachlorobenzene),Dieldrin (1,2,3,4,10,10-hexachloro-6,7-epoxy-1,4,4a,5,6,7,8,8a octahydro-1,4,5,8 … …American Journal of Environmental Sciences, Vol. 4, Issue 6 · 31 Dec 2008 · 9,909 accessesView PDFCite
Research ArticleOpen accessIn the abstractPublic Perception of Local Communities towards the Sustainable Management of Laguna Lake, PhilippinesGlenn L. Sia Su, Julio CervantesCommon failures in resolving multiple use conflicts are attributed to the inability of institutions to recognize and incorporate people's perceptions towards the resource. This study aims to determine the local communities' perceptions and factors influencing their perceptions towards Laguna Lake and its sustainable management. Copies of a self-administered questionnaire were distributed to systematically selected householders situated near and far from … …American Journal of Environmental Sciences, Vol. 4, Issue 6 · 31 Dec 2008 · 7,262 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Review on Correlations between Fish Freshness and pH during Cold StorageK.A. Abbas, A. Mohamed, B. Jamilah, M. EbrahimianFreshness of fish in most markets was found to be the significant quality parameter. The state of fish freshness was assessed by various methods but most of them were costly, time-consuming and not user friendly tools which made the development of simple, easy, undemanding and reliable system for the evaluation of fish freshness unresolved goal. The findings of many researchers … …American Journal of Biochemistry and Biotechnology, Vol. 4, Issue 4 · 31 Dec 2008 · 11,132 accessesView PDFCite

Research ArticleOpen accessIn the abstractA Design Strategy for Volumetric Efficiency Improvement in a Multi-cylinder Stationary Diesel Engine and its Validity under Transient Engine OperationP. Seenikannan, V.M. Periasamy, P. NagarajThis paper proposes an approach to improve engine performance of volumetric efficiency of a multi cylinder diesel engine. A computer simulation model is used to compare volumetric efficiency with instantaneous values. A baseline engine model is first correlated with measured volumetric efficiency data to establish confidence in the engine model's predictions. A derivative of the baseline model with exhaust manifold, … …American Journal of Applied Sciences, Vol. 5, Issue 3 · 31 Mar 2008 · 7,502 accessesView PDFCite
