Dynamics in Neuronal Microcircuits
ISBN: 9783838376325 / Angielski / Miękka / 136 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. The neocortex is the most computationally advanced portion of the brain. It is currently assumed to be composed of a large number of "cortical columns" - intricate arrangements of cortical neurons approximately 300-500um in diameter and 2-5 mm in height in humans - that might serve as the elementary computational unit of the neocortex. Understanding the computation performed by this microcircuit is one of the keys to our comprehension of the brain. The so-called cortical column is not a static entity as it evolves throughout a lifetime and continually adapts to the information from its...

Blood Flow Analysis through Blocked Artery
ISBN: 9783838343969 / Angielski / Miękka / 112 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. In this study, different turbulence models like k-epsilon and k-omega SST model are tested by comparing them against experimental data given by Deshpande and Giddens 1976. The stenosed geometry of 75 % area reduction is used for comparison. CFD code FLUENT 6.2 is used to solve the flow equations and a steady state flow with 2D axi-symmetric geometry is considered with Reynolds number of 5000. For lamnar flow in CCA, Reynolds numbers 50, 100 and 200 were used and the results were compared with the experimental data as given by Ahmed Giddens and Mabon. The results for laminar study were also...

Digital management of locally suboptimal image quality in mammography
ISBN: 9783838380421 / Angielski / Miękka / 124 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. X-ray mammography is considered at present the most efficient, robust and cost-effective imaging strategy for the early detection of the leading cause of death in women, breast cancer. However, the significant complexity of breast anatomy results in suboptimal imaging of specific breast regions, such as breast periphery and dense mammary gland. The inhomogeneity of mammographic image quality can be dealt with by application of the so- called exposure or grey level equalisation techniques. This monograph provides the reader with a structured presentation of several equalisation ...

Aspects of Reproductive Biology and Pod Yield in Bambara Groundnut
ISBN: 9783838387628 / Angielski / Miękka / 108 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. Attempts to improve bambara groundnut through the conventional breeding methods have not been successful due to the failure of the crop to set seeds after artificial crosses. Thus, the available genotypes are selections from the aboriginal landraces. The architecture of the reproductive structures and longevity of the pollens grains may provide a clue to the possible causes of hybridization failure. Pollen viability and longevity are important physiological attributes that enable the breeder to understand species reproductive performance and therefore, enhance the successful implementation of...

Electrochemical Synchronization of Cell Spreading on Solid Surfaces
ISBN: 9783843360630 / Angielski / Miękka / 168 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. Cell synchronization is important for the analysis of molecular events involved in cell spreading and motility. Electrostatic interactions between cells and surfaces were investigated in order to synchronize the first step in cell adhesion. LimE- GFP marked Dictyostelium discoideum cells were used for fluorescent tracking of actin polymerization events. Oscillating LimE fluorescent peaks were observed for individual cells in standard phosphate buffer during spreading. At low ionic concentration (phosphate sucrose buffer 0.17 mM), cells levitate over the conductive surfaces (Indium...

The structure, function, and composition of the basement membrane of glomerular capillaries of the mammalian kidney have been extensively studied, in light of the membrane's frequent involvement in renal diseases. A novel mathematical model, based on the Fiber Matrix Theory, was developed to describe the dynamics of permselectivity of the glomerular capillary barrier using mainly its hemodynamic and morphometric variables. The glomerular basement membrane was represented as a homogeneous 3D meshwork of fibers of uniform length (L ), radius (R ), and packing density (N v) and characterized by...

Photodiagnosis of Oral Malignancy
ISBN: 9783838393735 / Angielski / Miękka / 196 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. Oral cancer represents a significant and growing concern worldwide due to its high prevalence. Early detection of neoplastic changes in the oral mucosa is the preeminent method to improve survival rates and quality of life of patients, because at these embryonic stages their eradicative treatment measures would be immense and more effective. Currently, most accepted clinical procedure for detection of oral cancer involves visual inspection and ensuing biopsy guided histological analysis, which is considered as "gold standard". However, this intact procedure is subjective, time...

Entropy and Syntropy
ISBN: 9783843392730 / Angielski / Miękka / 128 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. In 1925 the physicists Oskar Klein and Walter Gordon formulated an equation which unites quantum mechanics and special relativity. Studying the properties of the dual solution of this equation, the mathematician Luigi Fantappie found that the positive solution is governed by the law of entropy (from Greek en=diverge, tropos=tendency), whereas the negative solution is governed by a symmetrical law, which he named syntropy (syn=converge, tropos=tendency). Fantappie realized that the properties of the law of syntropy (concentration of energy, differentiation, order and organization), describe...

Unrevealing Endometrial Cancer
ISBN: 9783844332186 / Angielski / Miękka / 116 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. Traditionally, drugs were discovered by testing compounds synthesized in time consuming multi-step processes against a battery of in vivo biological screens. Promising compounds were then further studied in development, where their pharmaceutical properties, metabolism and potential toxicity were investigated. Here we present a study on herbal lead compounds and their potential binding affinity to the effectors molecules of major diseases like endometrial cancer. Clinical studies demonstrate a positive correlation between the extent of PDK1 and malignant progression of pre cancerous lesions...

Calcium Dynamics in Inner Ear Health and Disease
ISBN: 9783838304762 / Angielski / Miękka / 120 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. Calcium ion (Ca2+) acts as a fundamental signal transduction element in the inner ear, delivering information about sound, acceleration and gravity through a small number of mechano-transduction channels in the hair cell stereocilia as far as to the ribbon synapse, where it drives neurotransmission. The genetic approach is proving fundamental in unravelling the molecular basis of Ca2+ function in the control of these key cellular processes and it will undoubtedly pave the way to therapies for auditory dysfunctions in the years to come. Despite all the information provided by animal models and...
