In 1648, a Dutch physician named Johann Baptista van Helmont had essentially began the discovery of photosynthesis by experimenting with potted plants. With this experiment, he had grown a willow tree for five years. After testing, the mass of the tree had increased while the...

Introduction Laboratories can often have many potential hazards and require extra precautions to stay safe. Lab safety and procedure is crucial to ensure that you and anyone near your procedure or equipment and materials can remain safe and unharmed and can even prevent death. Lab...

A feedback loop is a biological occurrence wherein the output of a system amplifies the system (positive feedback) or inhibits the system (negative feedback). Living organisms are able to maintain homeostasis through these feedback loops. This is the mechanism that enables us to keep our...

Edward Prendick says in The Island of Doctor Moreau “What could it mean? A locked enclosure on a lonely island, a notorious vivisector, and these crippled and distorted men?…” (Wells). After finishing the book it is likely that the reader feels as confused about Moreau...

Introduction Watson and Rayner (1920) investigated classical conditioning, a behaviorist theory of learning. The researchers conditioned fear into little Albert and showed that fear can be learned. This research was ground-breaking as it demonstrated how phobias can be acquired at a young age. Although Albert...

Introduction Rare earth (RE) doped nanophosphors are widely used in light emitting diodes (LED’s), field emission displays (FEDs), scintillators, medical imaging and drug delivery. There exceptional electronic and optical properties are derived from f-f and f-d transitions. However, many reported synthesized nanophosphors degrade rapidly when...

Introduction The process of facial memory is crucial in real-life circumstances that it is involved in judiciary and laws. Despite the sophisticated mechanism of memory, inaccuracies can still be resulted by factors such as familiarity, attention, emotion, encoding and retrieval steps. In eyewitness identification task...

This experiment is carried out to observe the development of quail embryos within several days. The quail embryo usually develops and hatches in 20 to 21 days. We have conducted the experiment up until day 15, which it is consist of 16 eggs in total....

The growth of single crystals and their characterisation towards device fabrication have gained great momentum due to their significant applications in the fields of semiconductors, solid state lasers, non linear optics, piezoelectric, photosensitive materials and crystalline thin films for microelectronics and computer industries. In particular...

There have been many studies done on specific Taekwondo strikes and their kinetics or physics behind them. Through this experiment, I will be answering the questions: What line of impact is most effective when in combat and why? What makes this kick or strike so...

Beginning in 1927 and running through 1932, the Hawthorne Studies took place at the Western Electric Company’s Chicago Plant, who employed mostly women who assembled telephone equipment. The number one objective of the Hawthorne Studies was to examine how different work conditions affected employee productivity....

For this session, we began discussing the characteristics of scientific observations and experimentation, on the other hand, we conversed about the place of theories and models in science and the society. We kicked of the discussion with a bit of historical knowledge, learning about Greek...

Reduce noise in underwater for acoustic signal using different technology. There are some specified filter Wiener filter, Adaptive filter, and Wavelet Thresholding. Underwater acoustic telemetry exists in applications such as data harvesting for environmental monitoring, communication with and between manned and unmanned underwater vehicles, transmission...

In Goidel’s “America’s Failing Experiment: How We the People Have Become the Problem,” he expresses his concern for America and how living in a democracy with widespread and hardcore democratic values is contributing to the failure of our system. In his book, he analyzes the...

Introduction One of the zones with the most extreme conditions to live at for a plant has to be the shoreline. Vegetation that lives there gets flooded up to twice a day for a couple of hours. Not only do they have to be resistant...

Experiment no: -7 Aim: -To implementr case study on GSM. Theory: GSM is a standard developed by the European Telecommunications Standards Institute to describe the protocols for 2g digital cellular networks used by mobile devices such as smart phones,tablets. The GSM network can be broadly...

Jungle green is a muted more medium hue of green. To make any hue of green you need to mix equal amounts of the primary colours, blue and yellow to create your standard true green colour. However, to get to a jungle green you would...

Amongst many human behavior studies ever done, a very famous one, was one on obedience in psychology, the Milgram experiment. This was done by the psychologist Stanley Milgram, an experiment in which he focused on the complex conflict between obedience to authorities and the extent...

These are the bioreactors specialized for the fermentation that can be carried out either by exposing to sunlight or artificial illumination. Since artificial illumination is expensive, only the out of door photobioreactors are preferred. Certain important compounds are produced by employing photobioreactor Ex, B-carotena asthaxanthin....

For this lecture, I arrived a bit late because of the inclement weather. However, I did not miss much since the lecturer began with a revision of where we left off from last session. The lecture continued with us being presented with the approach that...

The scientific community is an international body of professionals that ultimately work in collaboration for the further progression of scientific discovery and application. It is because of this global network of interactions that occur between such scientists that individuals must make every possible effort to...

A scanning electron microscope provides details surface information about nanoparticle including morphological characterization, homogeneity and the size of the particles. Fig. 2 indicates the SEM micrograph of NiTiO3 nanoparticles. As can be observed the NiTiO3 nanoparticles present homogeneous morphology with spherical form and the average...

Everybody has heard about the soda and mentos science experiment where they drop mentos into different sodas and watch the explosions. This examination is fun and energizing and it has made us ponder about the science behind it. You may imagine that there is some...

High blood pressure is a significant public health concern. It is extremely widespread and a risk factor for numerous adverse health consequences, particularly coronary heart disease and stroke. The research conducted by the SPRINT group “A Randomized Trial of Intensive versus Standard Blood-Pressure Control; was...

Here in this paper an experimental study for the cooling of inlet air of natural draft dry cooling tower by water spray has been carried out to obtain the optimal solution for the development of cooling system of air. The experiments are performed on an...

Introduction If one was ever told that a government agency deceived a group of socioeconomic, disadvantaged, sick people and put them in an experiment where they never gave consent nor were, they ever treated of their diseases when the cure was made available. ‘Evil’, ‘cruel’,...

In experiment 8, “Acid-Base Equilibria,” quantitative values of acid ionization constants were taken by measuring the pH. The concept of buffer solutions resisting change in pH was also presented. When determining the dissociation constant (Ka) of Acetic Acid, the Titration curve was fundamental, thus a...

Computing is evolving constantly. New principles are discovered; older principles fall out of use. Experiments play an essential role in science. However, the role of experiments in computer science is still unclear. Questions about the relevance of experiments in computer science attracted little attention until...

The hydrophobic cotton surface is facilely fabricated by an easy novel method through adsorption of fluorosurfactant on the cotton surface and then polymerization of low-surface-energy fluoro monomer in the presence of an initiator under ambient temperature with a short time. By in situ introducing fluoropolymer...

Soil is a heterogeneous material with significant variations possible within a single sampling site due to different topography, farming procedure, soil type for an example is clay content, drainage and the underlying geology. Soil sampling can be done, for example, by using an auger, spade...
