The potential of The Trivedi Effect®-Consciousness Energy Healing vitamin D3 and DMEM medium was investigated in human bone osteosarcoma cells (MG-63). The Test Items (TI) i.e. vitamin D3 and DMEM were separated into two parts. Bone health parameters were tested such as Alkaline Phosphatase enzyme (ALP) activity, collagen levels and bone mineralization. The Test Items (TI) i.e. vitamin D3 and DMEM medium were divided into two parts. The test samples received Consciousness Energy Healing Treatment by Karen Byrnes Allen and samples were defined as the Biofield Energy Treated (BT) samples, while the other parts of each sample were denoted as the Untreated test items (UT). Cell viability using MTT assay exhibited increased cell viability more than 71% with safe and nontoxic profile among test samples on MG-63 cell line. The level of ALP was significantly increased by116.4% at 50µg/mL in the UT-DMEM+BT-TI group, while 35.6%, 81.2%, and 47.9% at 10, 50 and 100 μg/mL, respectively in the BT-DMEM+UT-TI group. In addition, ALP level was increased by 42.3% and 90.6% at 10 and 50 μg/mL, respectively in the BT-DMEM+BT-TI groups as compared with the untreated group. The level of collagen was significantly increased by 10.5% and 110.1% at 0.1 and 1 μg/mL, respectively in the UT-DMEM+BT-TI group, while 22.6% and 190.6% at 0.1 and 1µg/mL, respectively in the BT-DMEM+UT-TI group as compared with the untreated group. In addition, BT-DMEM+BT-TI group showed a significant increased collagen level by 140.6% and 39.9% at 0.1 and 1 µg/mL, respectively as compared with the untreated test item and DMEM group. The percent of bone mineralization was significantly increased by 128.7% at 50 μg/mL, in the UT-DMEM+BT-TI group, while 34.1%, 154.7%, and 18.7% at 1, 10, and 50 μg/mL, respectively in the BT-DMEM+UT-TI group as compared with the untreated group. In addition, BT-DMEM+BT-TI group showed a significant increased bone mineralization by 105.7%, 78.1%, and 39.6% at 1, 10, and 50 μg/mL, respectively as compared with the untreated group. Thus, the study results concluded that The Trivedi Effect® Treatment would be the best alternative treatment for the maintenance of strong and healthy bones and quality of life. Further, it regulates the osteoblast function and improved the level of collagen, ALP, and calcium absorption in wide range of bone disorders along with wide range of adverse bone health conditions.

Physical Chemistry 2
Conditions of Use:

The module, Physical Chemistry 2, focuses on six (6) areas of physical chemistry important to many aspects of our lives: solutions, colloids, phase equilibrium, electrochemistry, nuclear and quantum chemistry. Solutions are often necessary to facilitate many chemical reactions that are important to life, and/or for industrial processes; while colloids find extensive applications in various chemical industries (e.g., in pharmaceuticals, food and beverages, paints, adhesives, cosmetics, inks and many other industrial products). The applications of electrochemistry are wide spread with great economic significance. A number of real life processes also involve electrochemical reactions, the knowledge of which allows us to understand certain chemical and biological reactions related to them. Rusting of iron, bleaching of stains and photosynthesis are examples of such life processes. Many substances exist in more than one physical state, the most common being solid, liquid and gas phases. Each of the phases has significantly different physical properties, knowledge of which can be used for our benefit in different circumstances. As you may or may not know, although the nuclei of many isotopes are stable, some are however unstable and will undergo what is known as a nuclear reaction. Such reactions although useful in certain applications, like electricity power generation and nuclear medicine, yet nuclear reactions could also be harmful and destructive as with its application in producing the atomic bomb- a weapon of mass destruction. Elementary particles (photons, electrons, neutrons, protons, etc) configure with the forces of nature to make all forms of matter. Thus, the internal structures of these particles determine the chemical and physical behavior of matter and in turn, influence the nature of their interaction with radiation. The constructive interpretation of this kind of reaction using quantum chemical and mechanical principles provide useful framework for their application in the development of modern technologies. Solar energy panels, automatic doors, elevators, pocket calculator and intrusion alarms are some of the products of processes related to quantum mechanical ideas.

The process of integrating ICT in education is rarely a simple and linear one - overlaps are often noted, with some elements operating in parallel, in partnership and cyclically. The sequence of steps varies from one activity or situation to the next and must take context into account in order to be effective. The process is thus necessarily incremental and relies on clearly defined objectives to succeed in improving the efficiency of ICT use in education. This document presents major themes to assist educators in better integrating ICT with their teaching, and particularly allowing them to offer higher quality distance education programs to Mathematics, Biology, Chemistry and Physics students. An introduction to the theories and principles of ICT integration is presented within six themes, and further developed into seven specific learning objectives, which can be adapted according to the specific subject of the program.

The ability to manage, lead and supervise students during the learning process has been shown to be an indispensible component of effective teaching and learning, more so in Sub-Saharan Africa where the challenge of overcrowded classrooms hinders effective teacher instruction in the classroom. For the classroom to serve its purpose, the teacher must be able to establish order. This requires him/her to have the knowledge, attitude and skills necessary. He/she must be able to establish rapport with the students and their parents, involve students in the processes of establishing ground rules for behaviour and being accountable for their actions, manage transitions during instructions, and motivate students to maximize time-on-task, supervise students in their learning activities and lastly deal with students’ misbehaviour effectively. This module is expected to help students master these key skills. It will also equip them with the ability to be open-minded and creative about the application of these techniques to their challenges.

This module starts by defining industrial chemistry and then gives a view of the chemical industry, its position in the general economy, and its classification in terms of the chemical processes that characterize it. To enable the study of selected chemical processes, unit operations and unit processes, especially those that are relevant in later learning actvities, are then covered in Unit 2. With this background, it will be easy to study industrial inorganic and organic chemical industries. The study of extractive metallurgy in Unit 3 draws on the knowledge of size reduction and separation unit operations learnt earlier, as well as chemical conversions that take place during pyroprocessing. The extractive metallugy of iron, copper and aluminium is included. In Unit 4, we focus our attention on some basic inorganic industrial processes that synthesize products from a variety of raw materials derived from the natural environment. They include manufacture of chlorine and sodium hydroxide from brine, ammonia from methane and nitrogen, sulphuric acid from sulphur, fertilizer and cement from mineral ores. The study of organic industrial chemistry then starts with petroleum refining followed by the manufacture of selected petrochemicals and polymers. The module closes with the study of ethanol, pharmaceuticals, soaps and detergents. These are high value-added products, some of which are produced through the fermentation route.

Solving Complex Problems addresses complex multi actor systems; so called ‘spaghetti situations’ in which everything is connected to everything, and everything influences everything. Situations, for instance, in which innovative new energy technologies emerge into the existing energy system. Or new health technology, medicine, treatments or screening technologies are being developed and society has to decide about whether they should be allowed and what they may cost.

This course has been awarded with the Award for Open Education Excellence in 2015 and has been shortlisted for the Wharton Awards in the category of Hybrid Learning in 2014.

What to do about expanding international airports that have the habit of developing closely to densely populated areas? These airports are believed to contribute substantially to the economy and industrial activity in a country but also generate substantial hindrance when it comes to noise and local air quality. What to do about the multi-facetted and multi-subsystem linkages of the ICT based emergency response system in a country, where at different places decisions have to be made that may influence the safety of people substantially.

In situations such as the above, it is by far not obvious what the best solution is. All people involved have a different idea about what the solution should be. And if you ask them, all these people have different ideas about what the problem exactly is either. If you, as engineer, consultant, manager, policy maker, politician or analyst are in a situation like this, then what to do?

There are multiple ways, but one option that has proven to be very useful is the analytical, engineering like approach of analysing the problem, a methodology for making the problem explicit and rationalising the different potential solutions. In short: analytically based support of decision making, design and implementation of solutions.
