Blog #8

For this blog, we were asked to write about someone who was buried in one of the following cemeteries  Riverside or Rose Hill. The individual I want to write about is Mrs. Ruby Davidson Williams.

Mrs. Ruby Davidson Williams

from Riversidecemetery.com

She was born Ruby Davidson on August 19, 1927. She was a native of Laurens County. She was married to Mr. Al Williams and had two sons. She was a very involved individual, having been involved with United Methodist Women (as a member), Mission Study Group, and the Past Matrons Club of Macon. She also served as a secretary of Elbert Order 215 of the Order of the Eastern Star. She also served as the Vice President of the Macon Woman's Club. She died on October 11, 1976 at the age of 49. She was buried the next day (October 12, 1976). She was survived by her husband, her sons, her mother, and many of her siblings. She was a very involved person in the Macon community.

Mitochondrial Eve

Mitochondrial Eve is thought (by scientists) to be the most recent woman that all humans are descended from. The reason she is referred to as Mitochondrial Eve s because each person receives 100% of their mitochondrial DNA from their maternal line (mother), unlike cellular DNA where half of the content comes from the maternal line and the other half from the fraternal line. It is believed that Mitochondrial Eve lived over 200,000 years old in the eastern portion of Africa.

Diversity of People

It is believed that Mitochondrial Eve lived in Eastern Africa. From that originating point, there were probably a number of cohorts of people that migrated to different areas which created human diversity. In different parts of the Earth certain biological traits are necessary for optimal living and some are not. As the people in the particular cohorts began reproducing, some traits were retained, some new traits were developed, and some were no longer passed along. 

Examples of Diversity

One would assume this person to be of Asian descent because of the "slanted" eye feature as well as the darker colored hair. 

One would assume this person to be of African descent because of the dark skin tone as well as the full lips feature.

One would assume this person to be of Indian descent (Asian, not Native American) because of the brown skin tone, large eyes dark hair color, and straight nose.

One would assume this person to be of Hispanic descent because of the thick eyebrows, browner skin tone, dark hair, and brown eyes.

One would assume this person is of Irish descent because of the "red" hair as well as the freckles.

Granite

Most granite is in the SiO2 (silica) form. Granite is a common widely occurring type of intrusive, felsic, igneous rock which is granular and crystalline in texture. This rock consists mainly of quartz, mica, and feldspar. Occasionally some individual crystals (phenocrysts) are larger than the groundmass, in which case the texture is known as porphyritic. A granitic rock with a porphyritic texture is sometimes known as a porphyry. Granites can be pink to gray in color, depending on their chemistry and mineralogy. By definition, granite is an igneous rock with at least 20% quartz by volume. Granite differs from granodiorite in that at least 35% of the feldspar in granite is alkali feldspar as opposed to plagioclase; it is the alkali feldspar that gives many granites a distinctive pink color. Outcrops of granite tend to form tors and rounded massifs. Granites sometimes occur in circular depressions surrounded by a range of hills, formed by the metamorphic aureole or hornfels. Granite is usually found in the continental plates of the Earth's crust.

Gneiss

Gneiss is a common and widely distributed type of rock formed by high-grade regional metamorphic processes from pre-existing formations that were originally either igneous or sedimentary rocks.

from http://en.wikipedia.org/wiki/Gneiss

Coquina (Shellstones)

Coquina is a sedimentary rock that is composed either wholly or almost entirely of the transported, abraded, and mechanically sorted fragments of the shells of either molluscs, trilobites, brachiopods, or other invertebrates. For a sediment to be considered to be a coquina, the average size of the particles composing it should be 2 mm or greater in size. Coquina can vary in hardness from poorly to moderately-cemented. The term "coquina" is derived from the Spanish word for cockleshells or shellfish. Incompletely consolidated and poorly cemented coquinas are considered grainstones in the Dunham classification system for carbonate sedimentary rocks. Well-cemented coquinas are classified as biosparites according to the Folk classification of sedimentary rocks.

Quartz

Quartz is an abundant mineral in the Earth's continental crust. It is made up of a continuous framework of SiO₄ silicon–oxygentetrahedra, with each oxygen being shared between two tetrahedra, giving an overall formula SiO₂. There are many different varieties of quartz, several of which are semi-precious gemstones. Throughout the world, varieties of quartz have been, since antiquity, the most commonly used minerals in the making of jewelry and hardstone carvings.

Feldspar

Feldspars (KAlSi₃O₈ – NaAlSi₃O₈ – CaAl₂Si₂O₈) are a group of rock-forming tectosilicate minerals which make up as much as 60% of the Earth's crust. Feldspars crystallize from magma in both intrusive and extrusive igneous rocks, as veins, and are also present in many types ofmetamorphic rock. Rock formed almost entirely of calcic plagioclase feldspar (see below) is known as anorthosite. Feldspars are also found in many types of sedimentary rock.

Hornblende

Hornblende is a complex inosilicate series of minerals (ferrohornblende – magnesiohornblende). It is not a recognized mineral in its own right, but the name is used as a general or field term, to refer to a dark amphibole. Hornblende is an isomorphous mixture of three molecules; a calcium-iron-magnesium silicate, an aluminium-iron-magnesium silicate, and an iron-magnesium silicate. The general formula can be given as (Ca,Na)_2–3(Mg,Fe,Al)₅(Al,Si)₈O₂₂(OH,F)₂.

from http://en.wikipedia.org/wiki/Hornblende

Mica

The mica group of sheet silicate (phyllosilicate) minerals includes several closely related materials having close to perfect basal cleavage. All are monoclinic, with a tendency towards pseudohexagonal crystals, and are similar in chemical composition. The nearly perfect cleavage, which is the most prominent characteristic of mica, is explained by the hexagonal sheet-like arrangement of its atoms.

For our third lab, we took a walk around campus and learned a great deal about the trees, shrubs, and flowers that we typically walk past everyday.

Among the scrubs, we saw...

The Loropetalum

This plant is also known as the "Chinese Fringe Flower." It is popular in the southeastern portion of the United States. It grows best in a rich, acid loam that is drained well.

http://landscaping.about.com/od/evergreenshrubsbushes1/p/loropetalum.htm

The Itea Shrub

The scientific name for this plant is "Itea Virginica." This scrub is primarily found in the southern portion of the United States. This plant is also known as the "Virginia Sweetspire" and the "Virginia willow."

The Pecan Tree

The scientific name for this tree is "Carya illinoinensis." This tree can be found in the southeastern United States, Ohio, and New Mexico among other places. Thomas Jefferson actually planted Pecan trees. This tree is also the official state tree of Texas.

http://en.wikipedia.org/wiki/Pecan

The Dogwood

It has a scientific name of "Cornus florida." This tree is adaptable to growth in many different soils. It is found in the southeastern portion of the U.S.

http://en.wikipedia.org/wiki/Cornus_florida

And among the flowers, we saw...

The Day Lilies

The scientific name for this flower is "Hemerocallis" The scientif name is derived form two Greek words, meaning "beauty" and "day." These flowers can be drought tolerant when needed.

The Marigold

This flower has a scientific name of " Tagetes." These flowers can have a musky fragrance. They can be a great nectar source for butterflies.

http://en.wikipedia.org/wiki/Tagetes

The Verbeana Latana

These flowers are mostly used as ground covers, though they can grow to be six feet tall. They are native to the American tropics. Flowers are born throughout the year in areas that are frost-free.

These plants are some of the plants that make up the environment around the Mercer University campus, as well as portions of the southeastern United States.

Blog #2

For our second lab, we took a trip to the Ocmulgee River to run some observe the landscape, as well as run some tests in the river. We looked to measure the elevational differences in the different areas along the river bed. We also measured the amount of clams that lived in certain areas of the water. Finally, we measured the flow rate of the river using simple objects.

1. Measuring the elevational differences - We did not get the opportunity to measure the elevational differences However, if we did measure the levels we would have measured the elevational differences by using PCB pipes and reading the line levels that are marked on it. One pipe with markings on it would be tied to another pipe like it. Then you would take the numbers from the pipes and subtract them to get the elevation increase or decrease. One mark on the pipe equals one foot.

2. Measuring the relative amount of clams in river - We used a large crate with a metal screen in the bottom. We dug up some sand from different areas of the river and placed the sand in the crate. Then the sand was sifted through the metal screen, revealing the clams. Then the number of clams was counted and we took counts for different elevations to see the clam concentrations in certain types of areas (ex. deep underwater sand vs. island sand).

3. Measuring the river flow rate - We found a small object to float in the water. Then we spaced people out in even intervals to see how much time it took the object to reach each person. Then the object was allowed to float along the river, passing by the people. Then we calculated the speed by taking the distance and dividing it by the amount of time it took to cover that distance.

Our Ocmulgee River Experience

Ocmulgee River Data

My Ocmulgee River Elevation Graph

So our trip to the Ocmulgee River helped us to see how to measure different constructs by measuring the clam concentrations, the river flow rate, and the different elevational levels of the river. Knowing these things about the river is important because the Ocmulgee River is such an integral part of the environment.

Cartography

Choropleth Map

The chloropleth map is good for visualizing a measurement's variation across an particular area. In this map we see can see where there are many acres of orchids and also areas that do not have a lot of orchid acres. 

Dot Density Map

The dot density map is useful because they can see spacial patterns of whatever the map looks to show. Each dot should be placed in a pinpoint location. It is also good in showing the concentration of something. For instance, in this map, we can see that the United States' harvested cropland in 1949 was mostly harvested in the Midwest.

Proportional Symbol Map

The proportional symbol map is used to show geographic information. Symbols on the map are generally not placed in pinpoint locations. In this map, we can see that the larger states have a higher number of high school dropouts.

Isopleth Map

Isopleth maps are good in showing a particular area's steepness as well as weather fronts that may be moving in an area. This map is unique because the lines are the focal point rather than dots, coloration, and symbols. In this example, we can see there are a few steep spots in the area and we can also see the elevations.
