It seeks to classify and research on chemicals. A lab instrument that is used to carry out this research is the Fourier transform infrared spectrometer. The Fourier transform Infrared spectrometer gives an electromagnetic spectrum that is
The respiration done by plants and animals reduces the concentrations of oxygen while photosynthesis increases the oxygen concentrations. Therefore the primary productivity of an ecosystem can be measured over
One of the most common methods of measuring the mechanical properties of a material is through a tensile test. The test consists of loading a specimen of known dimensions in tension, with the loading force being gradually
Mentally note the Sun-Earth-Moon positions. Where is the dark side of the Moon? Facing away from sun Where is the far side of the Moon? Facing away from sun_
Position yourself and the Moon so that the Moon is in its 3rd quarter phase.
The studies have found that a biallelic VNTR (variable number tandem repeat) polymorphism is present in the human PER3 gene at the chromosome 1p36.23, and it contains two alleles with 4 or 5 tandem repeats of 54 bp.This VNTR was evaluated as the important genetic factor for the chronotypes as it is associated with the diurnal preference.
Nevertheless, it is easier to switch between the views. Moreover, one can obtain specific information, capture or get new data, clear the data, or save the information for viewing in a later time. This is enabled by search, save and clear buttons that
ASTM C 150 gives the standard specifications for Portland Cement.
The apparatus used included Fine aggregate, Portland type 1cement, Molds for mortar cubes, scale, measures, testing machine, tamper, trowel, moist cabinet, mixer, bowl and paddle. The
rges, the magnetic field can also exert a force on a current and for a straight wire with length L carrying current I, the magnitude of the force that is exerted by the magnetic field B is given by:
From the lab experiment carried out above, the objectives have been met and the
Then we jumped onto the era of internet where most of the needs of the day are resolved using internet itself. Few individuals now can be seen doing the transactions standing at the bank. But, as the wise people say “There are no free lunches”,
Very interestingly, the growth and expansion show in almost every major industry. Tourism exhibits undeniable advancements.2 Agriculture demonstrates new potentials3 while the mining4 sector continues to be undaunted by
The refraction is viewed as a change in direction when light changes speed as it travels between materials of different densities. For instance, when light travels from air to water it will have a bending effect on the light as a result of the change in
The resistance of a tin coated glass was measured using a multi-meter so as to identify the conducting surface. With the identified conducting side facing upwards, the glass was taped on three sides using the same thickness of tape. Fingerprints or oils were then wiped off
Test sound of various frequencies can be generated depending on the patients hearing threshold and response. Audiological investigations help tremendously in diagnosing the nature of deafness and disorder
The magnitude of that force depends on the objects velocity, increasing with increasing velocity. The underlying law is derived empirically rather than based on theory. For most situations, simple approximations usually suffice; the simplest one of them is the
The bacterial physiology, Gram’s staining method, Microscopic examination, colony morphology, cellular morphology; biochemical testing and DNA sequencing are the methods that will help us to identify the
The changing positions result in its light being felt differently on earth. For instance, at times it is stronger and its light is felt for longer (Lang 66).
When the moon is in between the sun and the earth as shown in picture eight, its effects are not felt.
This law states that if the right handed screw moves forward in the direction of the conventional current, the direction of rotation of the screw gives the direction of the field. Moving electric charges create magnetic fields B described
However, there exist some bacteria that are resistance to numerous antibiotics. Collins (2002) describes them as MDR (multidrug resistant) or superbugs. Multiple researchers have categorized drug resistance as
This paper elaborates an engineering project carried out by Mechanical Engineering Students. All of the engineering analysis was used to determine the material and the assembly of the device based on a factor of safety. The final design specifications were based on comparisons with current machinery employing the same application e.g. cranes and wrenches.
Physical separation of starch granules is utilized in making Burre Manie through mixing and coating of starch within oil thus making them not to stick together. Starch normally sticks on each other thus its particles ought to be separated prior, which normally depend on
For example, when the volume was 15 liters, the jet momentum was 4.02739519 Kgm/s2. When the volume reduced by 5 liters, jet momentum also was reduced to 2.26211127Kgm/s2. This was seen in all the three vanes. The force on the vane also decreased at the same time.
More than 5000 companies across the globe are signatories to the UN Global Compact and respond to its 10 core principles. However, we are limited to just 2 principles in our discussion here. An explanation of the two principles goes as
This process is also distinguished by the intensity of colors on the chromatogram.
The main factors responsible for folding and stability of amino acids are the existence of non- covalent bonds and intermolecular interactions that might be
Metals are substances which lose electrons to form positive ions otherwise known as cations. Metals have different properties depending on the position of a particular metal in the periodic table. The physical properties
The SNP genomic distribution has no homogeneity. It always occurs in those regions that are non-coding. It has minimum occurrence in the regions that are coded. This is a case where the natural selection acts and fixes the SNP allele with favorable adaptation
Thereafter, the volatile liquid was heated in a water bath. The flask was tilted slightly to make it easy to see when all the volatile liquid had vaporized. Subsequently, the temperature of the water bath was
The water-cement paste properties are dependent on the cement characteristics and relative proportions of these components. The water-cement ratio is one most important factor that influences the strength of the resulting concrete product.
The author explains that a 555 timer based oscillator is a circuit that generates highly and clear free running waveforms. The output frequency of these waveforms can be adjusted by connecting an RC circuit with one capacitor and two resistors. This circuit is a type of the general relaxation oscillator which generates square waveforms.
The author of the paper explains that hall effect is the voltage difference in an electrical conductor which normally occurs when a magnetic field is applied to a rectangular shaped conductor at right angles when it is carrying electric current. Theoretically, hall effect is explained by the principles of Lorentz force.
Water shortage is a problem that is faced by residents of the Middle East. This is mainly caused by climatic changes and few water resources availabilities. It is, therefore, best for the administration in the region to encourage the use of ground water. This is major because this is the type that is not easily contaminated.
The author states that in Kirchhoff’s Voltage Law, the algebraic sum of the voltages across any set of branches in a closed loop is zero. However, for this to be true a current direction must be assumed. As one moves across a resistor voltages drops and therefore the value of that voltage should be taken as negative.
In essence, laboratory experiments are normally conducted in a careful manner in order to determine the mechanical properties of different materials when they reach breakage limit. Behavior of various mechanical materials
The author provides the simplest type of audio amplifier. This amplifier contains output transistors that conduct irrespective of its output signal waveform. This amplifier is known to be the most linear. The only disadvantage is that it has low frequency. It is mostly applied in areas where high linearity is needed and has enough power available.
