Morphological image processing Mathematical morphology (MM) is a theory and technique for the analysis and processing of geometrical structures‚ based on set theory‚ lattice theory‚ topology‚ and random functions. MM is most commonly applied to digital images‚ but it can be employed as well on graphs‚ surface meshes‚ solids‚ and many other spatial structures. Topological and geometrical continuous-space concepts such as size‚ shape‚ convexity‚ connectivity‚ and geodesic distance‚ were introduced

of the symptoms. The study of meningitis dates back to the 1960’s when the causative organisms were discovered and treatments were developed. Since then the mortality rate from bacterial meningitis has not changed much despite the introduction of new antibiotics and treatments (Hussein 360). In the case of bacterial meningitis no one casual organism causes all of the cases‚ but rather there are many that capable of causing it. Although there are many causal organisms‚ there are three that are

Bacteria Growth Requirements Microbiology Life as we now it has ended. What is left you ask? Well it is said the only thing that could survive an incident that could end our known way of life is a roach and a pack or Twinkies. In truth the great survivor would be microorganisms. Microorganisms can survive where most cannot due to their size‚ nutritional needs‚ energy requirements‚ and are very good at adapting to different environments (Black 2008). Microorganisms require two things to

LEARNING ENGLISH MORPHOLOGY FOR EFL LEARNERS Generally‚ we can mention that EFL (English as a Foreign Language) learners are those who learn English tend to achieve the particular purpose. For example‚ they can use English when travelling or to communicate with other people from whatever country‚ who also speak English. We can classify the students of English department into EFL learners‚ too. So‚ they need to be able to speak English well. One of the foremost aspect in speaking English is we have

Is Lupeol safe It would appear that lupeol shows no toxic effects at reasonable levels in mice. No adverse effects have yet been seen‚ and research is still at an early stage. We currently have no long term human use studies to base any assumptions on‚ nevertheless I’m sure we’ll start seeing those pretty quickly. I have to stress that many of the studies on lupeol are conducted either in the lab (in-vitro) or in the murine model (in mice) and don’t necceserily mean these effects will be translated

Basic Modes of Operation 2.1. Batch culture Batch fermentation refers to a partially closed system in which most of the materials required are loaded onto the fermentor‚ decontaminated before the process starts and then‚ removed at the end. The only material added and removed during the course of a batch fermentation is the gas exchange and pH control solutions. In this mode of operation‚ conditions are continuously changing with time‚ and the fermentor is an unsteady-state system‚ although in

identify an organism from a mixture of two unknown bacterial species. In order to accomplish this‚ I first plated my unknown mixture on Tryptic Soy Agar (TSA)‚ Columbia Naladixic Acid (CNA)‚ and MacConkey’s Agar (MAC) plates. After 48 hours of incubation‚ it was unclear that two different bacterial colonies had grown on my TSA plate. Only one type of colony was evident. However‚ it was apparent that I had successfully isolated two different bacterial species by examining my MAC and CNA plates. Only

Bacterial Diversity Project John FreesackSection A24 Kim Daffer‚ John Chang September 23‚ 2012 Introduction: Bacteria are everywhere. Some can be seen with the naked eye and some require a microscope but how do we distinguish one kind of bacteria from another? To answer this question‚ we were required to complete three bacterial labs that helped us to understand what microorganisms are and how to identify and classify them. Thus‚ the main purpose of this project is to identify our unknown microorganisms

Study of Bacterial Growth and Resistance Level to Certain Antibiotics INTRODUCTION Escherichia coli—better known as E. coli—is a gram negative‚ rod shaped bacteria. It is relatively harmless‚ but can occasionally cause food poisoning. It can also provide Vitamin K2. It prevents the establishment of pathogenic bacteria‚ and is associated with or found in the intestinal organ. The antibiotic that E. coli is resistant to is Penicillin. Bacillus subtilis—better known as B. subtilis—is known as

BACTERIAL TRANSFORMATIONS USING PVIB II. INTRODUCTION Transformation is the manipulation of a bacterial cell’s DNA in order to alter the cell’s genotype or phenotype by absorbing free DNA from its surroundings. In this lab‚ pVIB plasmid will be used. A plasmid is a segment of DNA that can incorporate itself into the bacterial DNA. Although is not required for growth of the bacterial cell‚ plasmids can provide advantages in stressful environments such as the ability to adapt as environmental
