  • Biological Waste Water Treatment
    Wastewater Management 18. SECONDARY TREATMENT Secondary treatment of the wastewater could be achieved by chemical unit processes such as chemical oxidation, coagulation-flocculation and sedimentation, chemical precipitation, etc. or by employing biological processes (aerobic or anaerobic) where bacteria are used as a catalyst for removal of pollutant. For removal of organic matter from the wastewater, biological treatment processes are commonly used all over the world. Hence, for the treatment of wastewater like sewage and many of the agro-based industries and food processing industrial wastewaters the secondary treatment will invariably consist of a biological reactor either in single stage or in multi stage as per the requirements to meet the discharge norms. 18.1 Biological Treatment The objective of the biological treatment of wastewater is to remove organic matter from the wastewater which is present in soluble and colloidal form or to remove nutrients such as nitrogen and phosphorous from the wastewater. The microorganisms (principally bacteria) are used to convert the colloidal and dissolved carbonaceous organic matter into various gases and into cell tissue. Cell tissue having high specific gravity than water can be removed in settling tank. Hence, complete treatment of the wastewater will not be achieved unless the cell tissues are removed. Biological removal of degradable organics involves a sequence of steps including mass transfer, adsorption, absorption and biochemical enzymatic reactions. Stabilization of organic substances by microorganisms in a natural aquatic environment or in a controlled environment of biological treatment systems is accomplished by two distinct metabolic processes: respiration and synthesis, also called as catabolism and anabolism, respectively.

Lifespan refers to the life expectancy or longevity of an individual. The period from birth to the natural death of an organism known as its life span. Reproduction: Reproduction is defined as a biological process in which an organism gives rise to young ones (offspring) similar to itself. The offspring grow mature and in turn produce new offspring. Thus there is a cycle of birth, growth and death. The main purpose of reproduction are to: continue and preserve the specie pass species genetic identity keep the evolutionary chain going Page 1 of 21 Types of reproduction: Based on whether there is participation of one organism or two in the process of reproduction, it is of two types. Asexual reproduction: When offspring is produced by a single parent with or without the involvement of gamete formation the reproduction is asexual. Sexual reproduction: When two parents (opposite sex) participate in the reproductive process and also involved fusion of male and female gametes it is called sexual reproduction. ASSIGNMENT Q.1. Why is reproduction essential for organisms? Q.2. Which is better mode of reproduction: sexual or asexual? Why? MULTIPLE CHOICE QUESTIONS : - Q.1.

  • Mathematical Modeling of Complex Biological Systems
    Mathematical Modeling of Complex Biological Systems From Parts Lists to Understanding Systems Behavior Hans Peter Fischer, Ph.D. To understand complex biological systems such as cells, tissues, or even the human body, it is not sufficient to identify and characterize the individual molecules in the system. It also is necessary to obtain a thorough understanding of the interaction between molecules and pathways. This is even truer for understanding complex diseases such as cancer, Alzheimer’s disease, or alcoholism. With recent technological advances enabling researchers to monitor complex cellular processes on the molecular level, the focus is shifting toward interpreting the data generated by these so-called “–omics” technologies. Mathematical models allow researchers to investigate how complex regulatory processes are connected and how disruptions of these processes may contribute to the development of disease. In addition, computational models help investigators to systematically analyze systems perturbations, develop hypotheses to guide the design of new experimental tests, and ultimately assess the suitability of specific molecules as novel therapeutic targets. Numerous mathematical methods have been developed to address different categories of biological processes, such as metabolic processes or signaling and regulatory pathways. Today, modeling approaches are essential for biologists, enabling them to analyze complex physiological processes, as well as for the pharmaceutical industry, as a means for supporting drug discovery and

  • The Complexity of Cell-Biological Systems
    THE COMPLEXITY OF CELL-BIOLOGICAL SYSTEMS Olaf Wolkenhauer and Allan Muir PREFACE The structure of the essay is as follows: Introduction: The complexity of cell-biological systems has an “inherent” basis, related to the nature of cells (large number and variety of components, non- linear, spatio-temporal interactions, constant modification of the components) and arises also from the means we have for studying cells (technological and method- ological limitations). Section 1: Ontological and epistemological questions are intertwined: to study the nature of living systems, we require modeling and abstraction, which in turns requires assumptions and choices that will influence/constrain what we can know about cells. We study cells, organs and organisms at a particular, chosen level,are forced to select subsystems/parts of a larger whole, and pick a limited range of technologies to generate observations. The study of cell biological systems requires a pragmatic form of reductionism and the interpretation of data and models is sub- sequently linked to a context. The framework to develop (mathematical) models is systems theory. Systems theory is the study of organization per se. While investigations into the structural (material) organization of molecules and cells have dominated molecular and cell biology to this day, with the emergence of systems biology there is a shift of focus towards an understanding of the functional organization of cells and cell populations, i.e., the processes (“laws” and “mechanisms”) that determine the cell’s or organ’s behavior. The necessity to select a level and subsystem, leads inevitably to a conceptual close in the theory of dynamical systems: by classifying observables into dependent, independent and invariant ones (parameters) we draw a boundary between an interior and exterior.

  • A Systemic Multi-Scale Unified Representation of Biological Processes in Prokaryotes Vincent J
    Henry et al. Journal of Biomedical Semantics (2017) 8:53 DOI 10.1186/s13326-017-0165-6 RESEARCH Open Access The bacterial interlocked process ONtology (BiPON): a systemic multi-scale unified representation of biological processes in prokaryotes Vincent J. Henry 1,2†, Anne Goelzer2*† , Arnaud Ferré1, Stephan Fischer2, Marc Dinh2, Valentin Loux2, Christine Froidevaux1 and Vincent Fromion2 Abstract Background: High-throughput technologies produce huge amounts of heterogeneous biological data at all cellular levels. Structuring these data together with biological knowledge is a critical issue in biology and requires integrative tools and methods such as bio-ontologies to extract and share valuable information. In parallel, the development of recent whole-cell models using a systemic cell description opened alternatives for data integration. Integrating a systemic cell description within a bio-ontology would help to progress in whole-cell data integration and modeling synergistically. Results: We present BiPON, an ontology integrating a multi-scale systemic representation of bacterial cellular processes. BiPON consists in of two sub-ontologies, bioBiPON and modelBiPON. bioBiPON organizes the systemic description of biological information while modelBiPON describes the mathematical models (including parameters) associated with biological processes. bioBiPON and modelBiPON are related using bridge rules on classes during automatic reasoning. Biological processes are thus automatically related to mathematical models. 37% of BiPON classes stem from different well-established bio-ontologies, while the others have been manually defined and curated. Currently, BiPON integrates the main processes involved in bacterial gene expression processes. Conclusions: BiPON is a proof of concept of the way to combine formally systems biology and bio-ontology.

  • Linking Molecular Imaging Terminology to the Gene Ontology (GO)
    Linking Molecular Imaging Terminology to the Gene Ontology (GO) P.K. Tulipano, W. Millar, J.J. Cimino Pacific Symposium on Biocomputing 8:613-623(2003) LINKING MOLECULAR IMAGING TERMINOLOGY TO THE GENE ONTOLOGY (GO) P.K. TULIPANO,1 W.S. MILLAR,2 J.J. CIMINO1 Department of Medical Informatics1, Department of Radiology2 Columbia University, New York, NY 10032, USA Email: [email protected], [email protected], [email protected] The rapidly developing domain of molecular imaging represents the merging of current advances in the fields of molecular biology and imaging research. Despite this merger, an information gap continues to exist between the scientists who discover new gene products and the imaging scientists who can exploit this information. The Gene Ontology (GO) Consortium seeks to provide a set of structured terminologies for the conceptual annotation of gene product function, process and location in databases. However, no such structured set of concept-oriented terminology exists for the molecular imaging domain. Since the purpose of GO is to capture the information about the role of gene products, we propose that the mapping of GO’s established ontological concepts to a molecular imaging terminology will provide the necessary bridge to fill the information gap between the two fields. We have extracted terms and definitions from an already published molecular imaging glossary as well as molecular imaging research articles, and developed molecular imaging concepts. We then mapped our molecular imaging concepts to the existing gene ontology concepts as a method to comprehensively represent molecular imaging. 1 Introduction Advances in medical imaging such as improved image resolution, new imaging agents, and experimental micro imaging devices, have stimulated interest in the in vivo assessment of molecular interactions and pathways.1 These advancements coupled with the latest genomic discoveries have led to the rapid development of the molecular imaging domain.

Importantly, as we move through the Anthropocene Epoch, where human-driven climate change threatens biodiversity, understanding how an evolving population responds to extinction stress could be key to saving endangered ecosystems. With a neutral, agent-based model that incorporates the main principles of Darwinian evolution, such as heritability, variability, and competition, the dynamics of speciation and extinction is investigated. The simulated organisms evolve according to the reaction-diffusion rules of the 2D directed percolation universality class.
