Introduction

Initially there were beliefs that, MMPs are jointly able to degenerate all constituents making up the extracellular matrix (ECM) together with basement membrane that confines their operations to tissue reconstruction as well as the preservation. Nonetheless, the contemporary studies also signify that MMP-1 is responsible for controlling the production or else the activation of the chemokines. At this point, it is critical to understand that MMP-1 is among other MMPs.
Similarly, the knowledge holds it that MMP- 1 cleaves a peptide bond beforehand a residue comprising of a hydrophobic adjacent chain, for instance Met and Leu. The other sideways chains cleaved ...

Introduction to Modeling of Engineering Systems

The model that my group has developed is based upon the separation and accumulation of solids which flow into a settling tank from a feed steam. During this separation procedure, the solid accumulates into the settling tank and the cleaner liquid product accumulates in a storage tank. The feed stream, containing solid particles in liquid, flows continuously to the settling tank, and solids are thus able to settle to the bottom as the liquid moves upward through the tank. A product stream leaves the tank; this stream contains a smaller fraction of solids than the field stream. Eventually the amount of solids which ...

Waste Management

Introduction
Dealing with waste has become an increasing concern nowadays, since it affects people’s life quality by impacting the health, it affects the aesthetics, it jeopardizes the ecosystems and in general, it negatively impacts the environmental sustainability. Domestic waste (generated by individuals) and commercial and industrial waste represent a quotidian aspect that authorities are aiming to handle, either through applying laws and guidelines for maintaining healthy and clean cities and villages, either by applying various technologies for actually managing the waste disposals. And the processes and technologies used to manage the various types of waste differ depending on ...

Re: A column to separate an Acetone-Methanol mixture

The objective of the project was to optimize the design of a column used to process a supply stream containing 35 percent acetone at 30oC. The optimized design should turn out a distillate product containing 0.75 mole fraction of acetone and 0.0010 fraction of bottoms acetone. The outcome of the experiment produced a distillate product containing 0.0079 molar fraction of acetone.

The molar fraction of acetone in the first inlet stream was determined to be 0.14 lbmol/min. Also, the total flow rate of the second inlet stream and the total gas flow rate were determined to be 61.84 lbmoles/min ...

Introduction to Modeling of Engineering Systems

A semi-batch mode operates the solids separation process by accumulating and settling solids in a storage tank. The cleaner product accumulates in the storage tank whereas the feed stream with solids flows into the settling tank. The clean liquid flows upward into the tank leaving the solid particles at the bottom. The product stream from the tank has smaller solids than those in the feed stream. The amount of solids keeps increasing in the settling tank as solids increase in the settling time. The exit stream accumulates in the collection vessel. The solids in the settling tank should be removed ...

“The expression of ampicillin resistance and luciferase enzyme genes by E. coli transformation using the pUC18 and lux plasmids”
Abstract
The transformation process allows the uptake of DNA from the environment, with the incorporation and expression of genes. During this process, changes in the DNA of the receptor cell occur, producing some selective advantages in some cases, such as resistance to antibiotics. pUC18 and lux plasmids were used to determine the transformation process in Escherichia coli. Cells were made competent by the addition of calcium chloride and heat shock in order to induce the incorporation of the ...

Abstract

In this lab, an RC circuit was set up and powered using a square wave from a function generator. The output was manipulated and examined and the results viewed on an oscilloscope. On the oscilloscope, the energy was seen in the way it is stored, delivered and manipulated in circuit elements. In the lab session also, the usefulness of an oscilloscope as a high-speed voltmeter was learned. How it monitors signals occurring in time intervals of microseconds and milliseconds.

Article 1: Radiation Associated Brainstem Injury

The tolerance of the central nervous system (CNS) to radiation treatment is significant to patient under treatment for metastatic or primary diseases associated with neck, brain and head. In most cases, brainstem injury is graded by most widespread toxicity criterion of the Cancer Therapy Evaluation Program based on symptoms. The first grade is considered mild, the second grade is moderate and without the capacity to interfere with daily living activities. The third grade presents extreme interference with the activities of daily living while the fourth grade is life threatening. The manifestation of severe radiation therapy induced central nervous system ...

Abstract

Transformation remains, and hugely significant tool in extending the borders of life sciences and medicine. It can be referred as fixing intracellular DNA into a bacteria or organism through the vector, thus transforming it. This paper uses plasmid pUC18, self-reproducing circular/spherical strands of genes that may be modified. After the bacteria absorb the vector, some proteins not usually synthesized will occur. In this study, a system has been developed to monitor the transmittance of different DNA (genes) from a genetically transformed strain of Saccharomyces cerevisiae to E. coli. This mechanism is centered on yeast strains that contain several integrated ...

Wet Sieve Analysis

Wet sieving analysis of soils is used to analyze particles that contain large amounts of silt and clay. The soil particles are washed to ensure that the fine-grained particles are separated from the coarse-grained ones. The extremely fine particles normally clump together and have difficulty in passing the # 200 sieve. In this experiment, the classification of soils is done in order to determine the percentage of soil particle that passes the # 200 sieve. The Wet analysis is used to determine the fine particles in the soil sample (“45Th Anniversary of The Journal, 16)

1. When the load on the specimen increases, the compression on the specimen increases. The longitudinal strain increases by increasing of the load value. The young’s modulus gets increases with the longitudinal strain. The load compresses because of the load.
2. When a compressive force acts on the specimen, two types of stain occur one is lateral strain and another strain is the axial strain. The specimen undergoes lateral strain to some extent. The lateral strain occurs due to the overload applied on the specimen, but the specimen undergoes more longitudinal strain than the lateral strain. The specimen ...

Day 1 - Cell Culture: At First an LB/amp plate was labeled with initials, the date, the name of the bacterial strain to be used (BL21) and the plasmid (pDHFR). Then 10 uL of reconstituted BL21-pDHFR was pipetted onto an LB/amp plate using sterile tip.The bacteria was streaked into four quadrants of the plate and after this it was covered immediately to avoid contamination. The plate was placed upside down inside the incubator overnight at 37°C and once colonies have grown to ~1 mm in diameter, they may be stored in a sealed bag upside down at 4ºC ...

Introduction

Composites are mixtures of at least two materials, such as reinforcing elements, fillers, and composite matrix binder. Compared to concrete and timber, composites are relatively lightweight. Different composites differ in form and/or composition on a macroscopic scale. Each component retainsits identity and does not dissolve or merge completely into one another.
Composites are not generally used as fibres by themselves. They are often impregnated with a matrix material that transfers loads to the fibresand protects the fibres from abrasion and environmental attack. The useful properties of composites are diminished by the matrix to some extent but not fully.
Thermoset ...

The following report will be based on the ancient Babylonian Numeration System. It has a great deal of mathematics involved and continually relates to modern everyday life experiences. The history behind this number system goes way back to the ancient times when it first originated in 1800 BC. (Babylonian Numbers, n.d)

Babylonian mathematics developed from Mesopotamia, the country between the Euphrates and Tigris, known as Iraq today. In the late nineteenth century archaeologists began digging in the ancient city of Mesopotamia, and thousands of clay tablets were discovered in evidence of ancient civilizations. There was some recognition of the relation ...

Introduction

Solar heaters have been popularized in recent years for use in tertiary and residential areas. This has happened mostly in the third world countries. The reason behind this encouragement to use solar heaters is the reduction of cost and improving the performance. This has necessitated the use, and testing of solar heaters to produce hot water. The solar heater is fundamentally made up of tanks that act as solar absorbers ad storage bases for warm water. This is used in glazing to profit the green house effect and the insulating cases. The solar heaters can be made from ordinary ...

Introduction

When it comes to control systems, the inverted pendulum system is something that stands out from amongst the rest. Linear control concepts such as stabilization of unstable systems can be demonstrated using the inverted pendulum. Since the system is intrinsically non linear, many non linear concepts can also be demonstrated using the inverted pendulum. This system has basically two equilibrium states, one stable and the other unstable. In the stable equilibrium state, the pendulum points downwards and in the absence of any controlling forces, it returns to its original state. In the unstable equilibrium state, the pendulum points upwards. ...
