In the spring of 2001 the hilly uplands immediately northwest of the modern city of Durres were for the first time investigated using the techniques of intensive surface survey. In total, an area of six square kilometers was explored and twenty-nine sites were defined, most of them new. Remains of Greek antiquity were plentiful and include unpublished inscriptions and graves. One site may be the location of a previously unknown Archaic temple. Included in this article are descriptions of the areas investigated, a list of sites, and a catalogue of the most diagnostic artifacts recovered. Patterns of settlement and land use are discussed and compared to those recorded by other surveys in Albania.
The Middle Proterozoic Jacobsville Sandstone, located on the upper peninsula, Michigan, is the youngest rift- related sedimentary unit in the 1.1 Ga Midcontinent rift. Although outcrops of the Jacobsville Sandstone along the Lake Superior shoreline and in river gorges are well studied, these outcrops represent stratigraphically only the upper 300-400 feet of the estimated 9,000 feet thick Jacobsville Sandstone. I used drill cores and newly-studied outcrop samples; 1) to characterize stratigraphically continuous sections; 2) to compare the Jacobsville Sandstone in subsurface with the Jacobsville Sandstone in outcrop; 3) to identify lateral and vertical variations in texture and petrographic composition within the Jacobsville Sandstone; and 4) to determine petrographic provenance of the Jacobsville Sandstone.
The purpose of this project was to develop a method to characterize polymers using size exclusion chromatography. Specifically, high performance liquid chromatography coupled with a refractive index detector (RID) was used. Polyethylene glycol (PEG) was used a standard for this method. The mobile phase used was dimethylformamide (DMF). Three different mixtures of PEG polymers with known molecular weights were analyzed to characterize the molecular weight of polyacrylic acid (PAA). After running all polymers, retention times were taken and plotted on the x-axis along with LogMp (molecular weight) on the y-axis. A calibration curve was created and plugged in the retention time of PAA to the line equation. We then, took 10 to the power of that number and calculated a molecular weight of 52292.97 g/mol. This method was shown to be an effective way to characterize polymers using PEG as a standard. Poly (methyl methacrylate), otherwise known as P(MMA), was also tested using the same method. The known weight of the polymer was 60,500 g/mol. After running the polymer, 23,000 g/mol was calculated to be the molecular weight. This molecular weight shows that certain parameters like polarity needs to be considered when running samples on the HPLC.

Abstract. Several basic relative invariants for homogeneous linear differential
equations were discovered during the years shortly after 1878. Also, a basic
relative invariant was found by Paul Appell in 1889 for a type of nonlinear
differential equation. There was little progress during the years 1892--1988 as
researchers who worked with homogeneous linear differential equations were
unknowingly handicapped by the standard practice of introducing binomial
coefficients in the writing of their equations. They thereby failed to develop
adequate formulas for the coefficients of equations resulting from a change of
the independent variable. Consequently, for relative invariants as the most
important kind of invariant, progress was stymied.
The notation was simplified in 1989, adequate transformation formulas
were developed, and explicit expressions were deduced in 2002 for all of the
basic relative invariants of homogeneous linear differential equations. In 2007,
explicit formulas were obtained for all of the basic relative invariants of a
type of ordinary differential equation involving two parameters m and n that
represent positive integers. When n = 1 and m >= 3, the formulas specialize to
provide all of the basic relative invariants for homogeneous linear differential
equations of order m; and, when m = n = 2, they yield all three of the basic
relative invariants for the equations of Paul Appell.
A general method developed in 2014 combines two relative invariants of
weights p and q for the same type of equation to explicitly obtain a relative
invariant of weight p+q +r, for any r >= 0. With that, the principal problems
about relative invariants have now been solved.
This monograph provides clear perspective about the reformulation begun
after 1988 and recently completed. Chapters 15 and 18 show how the major
difficulties confronting earlier researchers have been overcome.

Talk Title: Lessons From Publishing: Do Researchers in Developing Countries Receive Credit for Their Work?
My laboratory is working to better understand if scientists in developing countries, where the majority of plant biodiversity occurs, are receiving proper scientific recognition for their research in the form of authorship in the peer-reviewed literature. We are also interested in promoting shared, accessible data that may be used in future studies to make novel advancements in the biological field. Our research thus far indicates that many scientists in developing countries are not being included in the published literature as authors
