Synthesis of muramyl dipeptide analogues as immunomodulatory agents
(2018)Peptidoglycan occurs naturally in cell wall structures of almost all types of bacteria. Muramyl dipeptide (MDP) is a fragment of peptidoglycan, which consists of N-acetylmuramic acid that is attached to a dipeptide of ... -
Synthesis of novel Lipid A analogs as potential ligands for toll-like receptor 4
(2009)Lipid A, the glycolipid component of Gram-negative bacterial lipopolysaccharide has been shown to engage the Toll-like receptor 4 (TLR4) signalling pathway. While this signalling cascade results in cellular mediators which ... -
Synthesis, characterization and photocatalytic application of TiO2 nanosized particles / by Dongliang Liao.
(2007, c200)In this thesis, effects of surfactant composition and concentration on shape, size, zeta potential, and photocatalytic activity of TiO2 nanosized particles are reported. Spherical, cubic, rod, ellipse and leaf-like shaped ... -
Synthesized emulsifiers from kraft lignin and the role of mixing in oil-in-water emulsions
(2023)Oil-in-water emulsions are widely used in various industrial applications such as food, pharmaceuticals, and cosmetics. An oil-in-water emulsion is a colloidal system in which oil droplets are dispersed in water with the ... -
Synthetic approaches to five-membered heterocycles containing both ring and side-chain phosphorus atoms
(1983)A brief review of the importance and variety of symmetrical and unsymmetrical bisphosphines is given and the possible theoretical and synthetic value of bisphosphines in which one of the phosphorus atoms is included in ... -
Synthetic approaches to new heterocycles containing two phosphorus atoms
(1971)Reactions involving nucleophilic attack of tertiary phosphines and related compounds upon acetylenic systems have been reviewed and the literature has been covered to the end of 1970. In an extension of some of the ... -
Synthetic studies on chaksine
(1970)This thesis is concerned with the preliminary studies in the synthesis of a monoterpenoid alkaloid, chaksine. Diethyl methylmalonate was alkylated with 1,3-dibromo propane to give 2-(3-bromopropyl)-2-methylmalonate. ... -
Synthetic studies on chaksine
(1981)This thesis is concerned with the studies in the synthesis of a monoterpenoid alkaloid, chaksine. Ethyl 2-n~butyl-4-bromoacetoacetate (11) was treated with sodium azide to give ethyl 2-n-butyl-4-azidoacetoacetate (12), ... -
Synthetic studies on slaframine
(1980)Thjs thesis is concerned with the prelIminary studies in the synthesis of an indolizine alkaloid, slaframine. A Wittig reaction of 3-carbethoxypropyltriphenylphosophonium iodide (43) with 4-pentenal (44) gave ... -
System formulation for parallel circuit analysis
(2015-06-16)Advances in communication systems and VLSI circuits increase the performance requirements and complexity of circuits. During the design process, there is a need to perform computationally demanding numerical simulations ... -
System identification and control of a flexible manipulator
(2000)The Observabilty Range Space Extraction (ORSE) algorithm used to identify a an initially overparameterized discrete-time state-space model for a single-link flexible manipulator. A controller named PDPC is designed to ... -
System identification and optimization of fuzzy relation matrix models based on semi-tensor product
(2021)Generally, in real-world engineering disciplines a dynamical system is nonlinear, having multi-input and multi-output (MIMO) variables, and high level parameter uncertainties. Although there are many approaches proposed ... -
Systematic literature search on health promotion strategies for adults with intellectual disabilities
(2009)Intellectual disability (ID) is not a disease itself, rather it is a condition that is characterized by significant limitations in both intellectual functioning and adaptation in conceptual and practical skills (van ... -

(1982)The systematics of Cicindela sexguttata Fabricius and Cicindela patruela Dejean was studied. Various aspects of their holomorphology were considered, including: multivariate analysis of external characters, morphology ... -
The systems thinking paradigm and higher-order cognitive processes
(2014-12-12)The present study examined a new psychological construct we have coined “The Systems Thinking Paradigm.” The systems thinking paradigm describes a cognitive style with which one is more likely to understand that complex ... -
Tachistoscopic study of reading related operations in average readers and those experiencing difficulty
(1989)Thirty elementary school children were classified into equal groups of poor and average readers. In a series of four experiments, subjects were requested to provide vocal responses to tachistoscopically presented stimuli ... -
Tall oil production process and characterization
(2017)Existing kraft pulp mills have seen the necessity to branch out from traditional pulp and paper products to alternative value-added products such as bioenergy and biomaterials as a result of increasing competition in the ... -
