Microbubbles and Ultrasound
ISBN: 9783844301069 / Angielski / Miękka / 240 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. Microbubbles have been used for several decades as ultrasound contrast agents in diagnostic ultrasound imaging. However, their application in gene therapy as delivery vehicles has only recently been realised. The presence of microbubbles in close proximity to cells during ultrasound insonation can increase the efficacy of drug or gene delivery by inducing sonoporation. In this research project, experimental in-house microbubbles were used in order to establish the exact parameters that lead to sonoporation. Confocal imaging and 3-D reconstruction indicated the structure, morphology and...

Properties of Encapsulated Chlorophyll-a in Carboxymethyl Cellulose
ISBN: 9783844306392 / Angielski / Miękka / 100 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. The operation of Photosynthetic Biomaterials (PBMs) away from its native membrane environment reduces its energy transducing and photovoltaic efficiencies drastically. Such degradations are contributed to the biomaterials' loss of photo-functionality in displaced environments or as a result of reconstitution into unsuitable "artificial membrane" materials. The work involves development of suitable preparation of gel-like carboxymethyl cellulose solution as the artificial membrane to encapsulate Chlorophyll-a molecules so as to successfully mimic and retain its native spectroscopic properties...

Computational Models of Spike-Timing Dependent Plasticity
ISBN: 9783838315270 / Angielski / Miękka / 192 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. This thesis work consists in a theoretical and computational study of a recently-indentified type of synaptic plasticity, called "spike-timing dependent plasticity" (STDP). The thesis is articulated in three main parts. (1) A phenomenological model of STDP is introduced based on experimental data, and the biophysical plausibility of this model is analyzed. (2) This model is then implemented in an analog-neuron simulator, in which neurons are emulated by integrated circuits (ASICs). The behavior of elementary circuits of neurons interconnected with STDP synapses is analyzed and compared to the...

Probing Protein Structural Dynamics from Residual Dipolar Couplings
ISBN: 9783838303895 / Angielski / Miękka / 156 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. Residual dipolar couplings (RDCs) provide
explicit information of the molecular structure and dynamics in solution at atomic level. Full utilization of RDC datasets requires the acquisition under multiple aligning conditions, which remains experimentally challenging. We have illustrated in an application to ubiquitin that molecular alignment can be modified by varying the morphological characteristics of a composite medium, composed of ordered bacteriophage Pf1 particles embedded...

An Adaptive Evolution Strategy for Protein Folding
ISBN: 9783838374253 / Angielski / Miękka / 232 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. Proteins are a group of molecules involved in practically all biological functions that owe their versatility to the ability of binding structurally complementary ligands. Due to the limitations of experimental techniques, however, the number of resolved structures is lagging behind the number of known sequences, calling for the development of structural prediction algorithms. Since the native structure corresponds to the global minimum of the free energy function, the protein folding problem can be recast in a global optimization problem. Genetic algorithms (GA) are optimization tools that...

Exercise, Aging and Bone Tissue Quality
ISBN: 9783838366425 / Angielski / Miękka / 136 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. Fractures are the most frequent health problem associated with bone and represent a significant clinical and economic burden. Fracture risk is most often assessed through bone mass scans, which measure bone quantity. However, aging and interventions like exercise have a greater influence on fracture risk than variances in mass predict, indicating that skeletal integrity is affected by alterations in tissue quality, and not just quantity. Currently, there is no clear understanding of how bone tissue quality contributes to skeletal integrity or how it can be altered by external...

In the past decade, the problem of optimal power flow (OPF) for improving economy and security of power system operation has received much attention. The OPF problem solution aims to optimize an objective function such as the fuel cost via optimal adjustment of the power system control variables, while at the same time satisfying various equality and inequality constraints. Generally, the OPF problem is a large- scale highly constrained nonlinear nonconvex optimization problem with several objectives. In deregulated environment, OPF is of current interest of many utilities and it...

Physico-chemical properties of non and interesterified oil/fat mixture
ISBN: 9783838334141 / Angielski / Miękka / 160 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. Fats and oils are multi-component systems. To understand their functionality, combinations of physical and chemical analyses of the fat and oil have to be conducted. The rationale for the study of such systems is based on the potential for two methods of interesterification to produce different positional distributions of fatty acids which, in turn, create fats with different functionality. This study is timely in that interesterified fully hydrogenated fats and oleic acid rich blends are being considered as alternatives to hydrogenation to create partially solid fats with particular physical...
