Orchestrating cell separation in plants : what are the risks and benefits?
In this podcast, Professor Roberts from the School of Biosciences discusses his research into the mechanism responsible for regulating cell separation in plants. In particular how plants ‘shed’ parts of themselves such as leaves or fruit. Professor Roberts explores the potential application of his research, through prevention or encouraging of the ‘shedding’ process, agricultural harvests could potentially be increased or even synchronised. Professor Roberts also discusses the resistance
TALAT Lecture 3210: Continuous Casting
This lecture gives an overview about the possibilities to produce aluminium foilstock and wire-bar in a continuous way. Continuous casting is the preferred casting method in modern plants because it offers higher productivity. But there are limitations in the use of this technology because not all alloys can be cast. The product shows properties that can differ from conventional material. This lecture demonstrates the principal of operation; technologies for continuous casting; types of casters;
TALAT Lecture 2302: Design of Joints
This lecture provides a view of types of joints in aluminium structures and how to design and calculate frequently used joints. Basic structural mechanics and knowledge of design philosophy, structural aluminium alloys and product forms is assumed.
Coarse open celled aluminium foam produced by infiltration of sintered salt (FOAM-U-LIKE)
FOAM-U-LIKE (Foaming of aluminium metal using lightly interconnected kevelled elements) is a very inexpensive route for the production of coarse open celled foams. It allows a reasonable degree of control over cell size and shape, and results in relatively uniform morphology. The interconnectivity of pores can be controlled by varying the degree of sintering of the precursor. In this case, grains of 1-4mm diameter have been sintered at 600 degrees C for just 10 minutes, giving rise to lightly in
This popular maths talk gives an introduction to various different kinds of infinity, both countable and uncountable. These concepts are illustrated in a somewhat informal way using the notion of Hilbert's infinite hotel. In this talk, the hotel manager tries to fit various infinite collections of guests into the hotel. The students should learn that many apparently different types of infinity are really the same size. However, there are genuinely "more" real numbers than there are positive inte
TALAT Lecture 1501: Properties, Characteristics and Alloys of Aluminium
This lecture provides a survey of the aluminium alloys available to the user; it describes their various properties; it gives an insight into the choice of aluminium for a proposed application. In the context of this lecture not every individual alloy and its properties have been treated in detail, but rather divided into alloy types with reference to the most commonly used alloys. For further details on alloy properties the reader is referred to available databanks like ALUSELECT of the Europea
Adding Multimedia to Your Connexions Content
An explanation of how to add various types of multimedia objects to your Connexions content. Examples of some of the more common multimedia objects are included.
11.471 Targeting the Poor: Local Economic Development in Developing Countries (MIT)
This course treats public-sector policies, programs, and projects that attempt to increase employment through development-promoting measures in the economic realm, through support and regulation. It discusses the types of initiatives, tasks, and environments that are most conducive to equitable outcomes, and emphasizes throughout the understandings gained about why certain initiatives work and others don’t.
Seminole Campus Nature Park
http://www.youtube.com/user/StPetersburgCollege Students at St. Petersburg College and residents of Seminole now have a new venue to explore nature. SPC officials opened the first phase of its Natural Habitat Park and Environmental Center on Aug. 31 with a crowd of about 200 on hand who were not fazed by the morning heat. The park is located immediately north of the school's University Partnership Building and the Seminole Community Library. The first phase includes a pavilion with seating
12.110 Sedimentary Geology (MIT)
This course covers sediments in the rock cycle, production of sediments at the Earth's surface, physics and chemistry of sedimentary materials, and scale and geometry of near-surface sedimentary bodies, including aquifers. We will also explore topics like sediment transport and deposition in modern sedimentary environments, burial and lithification, survey of major sedimentary rock types, stratigraphic relationships of sedimentary basins, and evolution of sedimentary processes through geologic t
The Siren Song of Cancer Cells
The treatment of complex diseases like cancer may lie in grasping their mechanisms at all levels of biological hierarchy. Most research focuses on understanding how genes cause cancer from within a cell, but much can be learned from intercell interaction.
Benefits of the Online Poster Application: Glogster
This short video explains how it is better for the environment to use Glogster to make posters.
Web-based teaching as a performance enhancer in foreign language teaching in Sri Lanka
This paper discusses the results of a pilot study conducted at University of Kelaniya in integrating web-based teaching into the study programmes of German as a Foreign Language. Since German is not a language popular at secondary school level, student offering to read the language at the university commence language learning as beginners. Albeit the courses are designed to impart language knowledge to all students equally, the performance of the majority of students at examinations indicated th
A Republic, If You Can Keep It: A Look into Types of Government
This ten minute video deals with types of government and the Constitution. A good video that explains the difference between types of government and rulers. Students should have a note sheet with the various types of governments so that they can add information from this video to their notes. Some information is questionable and this video needs to be reviewed before showing it to students.
Scaling Galileo's Solar System - Size of the Globes
In this activity students determine the sizes of the various planets in the solar system, scaled such that the orbit of Saturn fits on campus. The students also compare the planet sizes, given the scale, to the grain sizes of different sediment types. Students recreate spreadsheets, shown in a Powerpoint module, with formulas that answer various pieces of the overall question. This module is the second in a series of four on the Galilean Solar System, and was designed for an undergraduate class
Tissue movement in bipopulation tumour cord growth
Simulation of tumor cord growth where conversion of the tumor to glycolytic (anaerobic) metabolism takes place under hypoxia. This video shows volume fraction of glycolytic cell population and velocity of tissue movement. Isolines show hypoxia limits for aerobic and anaerobic cell lines respectively. This video reflects work in progress and may be different from the final results.
Wireless Sensor Networks for Ecology
Field biologists and ecologists are starting to open new avenues of inquiry at greater spatial and temporal resolution, allowing them to "observe the unobservable" through the use of wireless sensor networks. Sensor networks facilitate the collection of diverse types of data (from temperature to imagery and sound) at frequent intervals -- even multiple times per second -- over large areas, allowing ecologists and field biologists to engage in intensive and expansive sampling and to unobtrusively
