Studies using culture dependent methods have indicated that enterococci, the fecal indicator used to monitor marine waters for the potential of enteric disease risk to swimmers, can be abundant in beach sands and may contribute to water column indicator exceedances. A quantitative PCR (qPCR) method for the Enterococcus genus was tested and applied to more rapidly determine the amount of enteroc...

Human bite mark evidence is often found in violent crimes. Due to the difficulties of physically comparing an injury site on elastic and curved skin surfaces to the teeth of a suspect, the authors have considered using salivary DNA evidence to identify the bite perpetrator. Several techniques were evaluated to determine the best method of recovering saliva from human skin before extracting geno...

The aim of this study was to evaluate different methods for Trichomonas vaginalis diagnosis during pregnancy in order to prevent maternal and perinatal complications. A total of 386 vaginal exudates from pregnant women were analyzed. T. vaginalis was investigated by 3 types of microscopic examinations direct wet mount with physiologic saline solution, prolonged May-Grunwald Giemsa (MGG) stainin...

Wet foams are used in many important technologies either as end or intermediate products. However, the thermodynamic instability of wet foams leads to undesired bubble coarsening over time. Foam stability can be drastically improved by using particles instead of surfactants as foam stabilizers, since particles tend to adsorb irreversibly at the air-water interface. Recently, we presented a nove...

The objective of the present investigation was to design suitable Immediate release tablet formulation of Aceclofenac by using cross carmellose sodium as super-disintegrant in four different concentrations i.e., 0, 4, 6, 8% w/w of tablet weight by two granulation methods i.e., Wet and melt granulation methods. The objective of the research was to compare the two granulation methods i.e., wet an...

Trichomoniasis is a common sexually transmitted disease with an estimated incidence of 4 million to 8 million cases a year in the United States. The most commonly used method of diagnosis is a direct microscopic observation (wet mount) of vaginal secretions and, although both rapid and inexpensive, the sensitivity of this technique is generally 50 to 70%. We developed an indirect enzyme-linked ...

Coal swelling in the presence of water as well as CO2 is a well-known phenomenon, and these may affect the permeability of coal. Quantifying swelling effects is becoming an important issue to verify the suitability of particular coal seams for CO2-enhanced coal bed methane recovery projects. In this report, coal swelling experiments using a visualization method in the CO2 supercritical conditio...

Vertical hydraulic gradient is commonly measured in rivers, lakes, and streams for studies of groundwater-surface water interaction. While a number of methods with subtle differences have been applied, these methods can generally be separated into two categories; measuring surface water elevation and pressure in the subsurface separately or making direct measurements of the head difference with...

In this chapter, we describe a few popular experimental methodologies that can be used to independently validate the results of a microarray experiment. In contrast to many of the other chapters in this book, the techniques described here are decidedly non-mathematical or statistical in nature. Instead, most of them utilize standard 'wet-bench' molecular biology protocols that have proven thems...
