The Merit Property comprises four mineral claims 1, hectares and contains seven anomalous zones of alteration and mineralization. Highlights from surface samples collected in each zone include:. A ground-based magnetic survey was also completed by in which covered the entirety of the Merit Property. This survey has been highly instructive and shows distinct corridors of low-magnetic responses that connect most of the target zones, suggesting a common fluid-delivery system and the potential for increased target sizes through future work.
This main zone of mineralization, Sullivan Ridge is characterized by strong silica and carbonate alteration of andesitic breccias that host a m wide, north trending, gold-bearing quartz vein zone that can be traced for more than 80 m. This area was the initial focus due to past discoveries that highlighted anomalous gold values across a dome-shaped hill. A trenching program in across this zone returned anomalous gold values of 7.
Sullivan Ridge was drill tested by two diamond drill holes in One drill hole returned two 0. In , 31 rock samples were collected at Sullivan Ridge and returned values from trace to 9.
The system remains open to the southwest and to the northeast. Although Independence has attempted to identify important factors that could cause actual actions, events or results to differ materially from those described in forward-looking information, there may be other factors that cause actions, events or results not to be as anticipated, estimated or intended. There can be no assurance that such information will prove to be accurate as actual results and future events could differ materially from those anticipated in such statements.
Independence disclaims any intention or obligation to update or revise any forward-looking information, whether as a result of new information, future events or otherwise unless required by law.

Red Pine Exploration Intersects 3. Mantaro Precious Metals Corp. Mantaro Silver Corp. Provides Exploration Update at Golden Hill. We shall now present the numerical results of the sensitivity function M defined by Figures 9 — 12 are produced from the slopes of Figure 5 — 8. In the experiments, one may measure both the NTS intensity change and spectrum red shift in identifying the unknown RI of the sensing medium.
Therefore, the linear relationship should apply only to a very small medium RI ranges, say less than 0. As shown in Figure 13 , the maximum figure of merit occurs for optimal value of R , about 3. We have derived analytic formulas for the transmitted intensity in a fiber-based sensor using gold nanorods as the surface plasmon resonance medium.
This study demonstrates many important design aspects based on the roles of various fiber and GNR parameters on the normalized transmitted signal NTS which is a strongly decreasing function of the medium RI n and sensing numerical aperture but a weakly dependent function of the GNR aspect ratio R.
The scaling laws and the FOM presented in this paper may serve as the guidelines for optimal designs in fiber-based sensors.

Special Issues. Academic Editor: Christian Brosseau. Received 28 Mar Revised 14 May Accepted 14 May Published 13 Aug Abstract This paper presents a normalized transmitted signal NTS of a fiber-based sensor using gold nanorods as the plasmon excitation medium of the evanescent wave. Introduction The use of metal nanoparticles in biomedicine includes bioimaging, biosensing, drug delivery, and diagnostics therapeutics of cancer cell [ 1 — 14 ].
Theory The basic structure of a fiber-based sensor is shown in Figure 1 , where the standing wave becomes evanescent wave when it propagates in the bared-fiber portion which is functionalized by gold nanorod GNR layer as the absorbing medium. Figure 1.

The PTK Scholarship is renewable each year provided you remain a full-time undergraduate student while maintaining satisfactory progress towards a bachelor's degree and a B 3. Application for this program is by invitation and requires supplemental documentation. Students who are accepted will be notified and the scholarship amount will be additional to any merit-based scholarship awarded.
In addition to the aforementioned scholarships, our Financial Aid Office houses information about additional scholarships for University of New Haven students. The Financial Aid Office will automatically consider students for these scholarships after the student has completed the financial aid process. Students are also encouraged to look for scholarships in their local community or through their parent's employer.
Available to First-Time Students.
