Research ArticleOpen accessIn the abstractFirst Report of Human Immunodeficiency Virus Type 1 Circulating Recombinant Form 02_AG Recombinant Strain of African Origin from North IndiaUjjwal Neogi, Vikas Sood, Arpita Choudhury et al.Problem statement: Human Immunodeficiency Virus Type-1 (HIV-1) displays extensive genetic diversity globally which poses a serious challenge in making efficacious vaccine and developing effective therapeutic interventions. HIV-1 epidemic in India is largely driven by genetic subtype C but lately a number of reports suggest the presence of circulating recombinant forms and unique recombinant forms from different states of India. Approach: … …Current Research in Medicine, Vol. 1, Issue 2 · 31 Oct 2010 · 6,737 accessesView PDFCite
Research ArticleOpen accessIn the abstractProsody Modification of Standard Arabic Speech Using Combining Synchronous Overlap and Add With Fixed-Synthesis Algorithm and Multi Level Discrete Wavelet TransformYkhlef Faycal, Bensebti Mesaoud, Bendaouia LotfiProblem statement: The objective of prosody modification is to change the amplitude, duration and pitch (F0) of speech segments without altering their spectral envelop. Applications are numerous, including, Text-To-Speech synthesis, transformation of voice characteristics and foreign language learning. Several approaches have been developed in the literature to achieve this goal. The main restrictions of these latter are in the modification … …Journal of Computer Science, Vol. 6, Issue 4 · 30 Apr 2010 · 6,836 accessesView PDFCite
Research ArticleOpen accessIn the abstractMolecular Mechanisms of Neurodegenerative Diseases Induced by Human Retroviruses: A ReviewBryan P. Irish, Zafar K. Khan, Pooja Jain et al.Problem statement: Infection with retroviruses such as human immunodeficiency virus type 1 (HIV-1) and human T cell leukemia virus type 1 (HTLV-1) have been shown to lead to neurodegenerative diseases such as HIV-associated dementia (HAD) or neuroAIDS and HTLV-1-Associated Myelopathy/Tropical Spastic Paraparesis (HAM/TSP), respectively. Approach: HIV-1-induced neurologic disease is associated with an influx of HIV-infected monocytic cells across the blood-brain … …American Journal of Infectious Diseases, Vol. 5, Issue 3 · 30 Sep 2009 · 14,888 accessesView PDFCite
Research ArticleOpen accessIn the abstractCocaine Exposure Results in Formation of Dendritic Varicosity in Rat Primary Hippocampal NeuronsHonghong Yao, Crystal Bethel-Brown, Anil Kumar, Shilpa BuchProblem statement: It has been well documented that drugs of abuse such as cocaine can cause enhanced progression of HIV-Associated Neuropathological Disorders (HAND), the underlying mechanisms mediating these effects remain poorly understood. Approach: In present study, we explored the impact of cocaine exposure (I and 10 μM) on the dendritic beading in rat primary hippocampal neurons. Using the approach of … …American Journal of Infectious Diseases, Vol. 5, Issue 1 · 31 Mar 2009 · 7,889 accessesView PDFCite
Research ArticleOpen accessIn the abstractSustainable Housing RenewalM. Sitar, K. KrajncFollowing the already proved models the sustainable planning culture is endangering several methods directed towards the needs of tenants in the existing post-war housing stock. The case-study of our project is the renewal of the multi stored building in the housing estate Metalna, Maribor/Tezno (1949). It is based on the sustainable renovation principle for the quality of sustainable housing in … …American Journal of Applied Sciences, Vol. 5, Issue 1 · 31 Jan 2008 · 7,249 accessesView PDFCite
Research ArticleOpen accessIn the abstractRelationship Between Shear Strength and Soil Water Characteristic Curve of an Unsaturated Granitic Residual SoilThamer Ahmed Mohamed, Faisal Hj. Ali, S. Hashim, Bujang B.K. HuatShear strength parameters are crucial for stability analyses of slopes against slope failures and landslides. The three shear strength parameters that are required to define a failure envelope of an unsaturated soil are c’ (apparent cohesion), Φ’ (effective angle of friction) and Φb (shear strength change with change in matric suction). A soil-water characteristic curve (SWCC) that relates the water … …American Journal of Environmental Sciences, Vol. 2, Issue 4 · 31 Dec 2006 · 7,350 accessesView PDFCite
Research ArticleOpen accessIn the abstractPhotocurrent and Photoluminescence Investigations of GaInNAs and GaInNAs(Sb) Quantum Wells Grown by Molecular Beam EpitaxyS. Ben Bouzid, F. Bousbih, A Hamdouni et al.We have investigated photocurrent (PC) and photoluminescence (PL) in sequentially grown GaInNAs/GaAs and GaInNAs(Sb)/GaAsSbN quantum wells. Photocurrent transitions are analyzed by theoretical calculations using envelope function formalism taking into account the strain effect and the strong coupling between nitrogen localized state and the GaInAs band gap. The results are consistent with a type I band alignment and a conduction band … …American Journal of Applied Sciences, Vol. 2, Issue 9 · 30 Sep 2005 · 6,475 accessesView PDFCite
Research ArticleOpen accessIn the abstractMechanical and Microstructural Characterization of Plasma Welded Joints of 18 Ni-300 Maraging Steels Subjected to RepairsPaulo Roberto Sakai, Deivid Ferreira da Silva, Milton Sérgio Fernandes de Lima et al.Among the ultra-high strength structural steels, 18Ni-300 Maraging steel is one of the most important for the naval and aerospace industries. For example, in the manufacture of motor envelopes Plasma Arc Welding-PAW processes are used with the keyhole technique. The joints are regions of high responsibility and undergo a non-destructive inspection according to the standardized technical criteria. If there is … …Journal of Aircraft and Spacecraft Technology, Vol. 5, Issue 1 · 19 Apr 2021 · 7,599 accessesView PDFCite
