Examining the Microlinks Technology Co., Ltd. UM-CAM Richard J
Examining the Microlinks Technology Co., Ltd. UM-CAM Richard J. Nelson Introduction I usually buy “show specials” at the Las Vegas January Consumer Electronics Shows that I have attended for over 40 consecutive shows. Last year I bought a Microlinks Technology UM-CAM USB microscope to test and explore. I used a five dollar bill as a subject to illustrate the capability of the UM-CAM in 2010. See: http://www.msscweb.org/public/articles/Exploring_a_New_Five_Dollar_Bill.pdf The 2 megapixel (1600 x 1200) UM-CAM is attractive because it is advertised to work both as a webcam and as a USB microscope. This year I once again visited the Microlinks Technology booth, ™ , and they said that they had improved their UM-CAM in three ways. 1. They now include a test film with the product - as seen in Fig. 7d. 2. The software is improved with added features including a scale and the ability to make measurements – not part of this article/review. 3. The holder and case have been improved (mostly cosmetic) - as seen in blue Fig. 1. TX! Photo Fig. 1 – Last year’s and this year’s CES Show Specials are compared. It is a USB microscope and a webcam. The UM-CAM is quite handy and easy to use with its wide range of focus from a few mm to several meters. It has its own white LED lighting for use in the very close microscope application. The four LEDs are brightness level controlled to fully off. See Fig. 1 above. Also see Fig. 2 which is a self- portrait made by photographing a mirror. -

An Illuminated Stage Richard J
An Illuminated Stage Richard J. Nelson A microscope is like a good car, it should be powerful and strong. Unlike a car, however, a good microscope needs an assortment of accessories which, in some cases, may be more expensive than the microscope itself. Many simple accessories may be assembled from everyday items and most microscope users improvise in one way or another. I bought three USB Microscopes at the 2011 CES Show in Las Vegas, and I have been evaluating them - see Fig. 1. As with most product categories you will find a full range of designs – cheap to robust. Electronics technology also gets added to the mix when USB microscopes are considered. You may spend less than $100 or you may spend over $1,000. It was the CES “show specials” (low end) that prompted me to evaluate these three USB microscopes. Fig. 1 – My three 2011 CES “show special” USB microscopes. The three designs are shown at the right. See Appendix A for additional details. Each one has its unique advantages and disadvantages. As a technical writer I frequently need to include photos of small items so I thought that perhaps having a small simple USB microscope handy might make capturing small subject images easier. The image quality of these designs are getting better each year and the highest resolution design I saw at CES (expensive) was 5 megapixels. My Nikon stereo microscope and Sony 10.2 Megapixel DSC-TX1 usually handles most of my small subject image requirements. In the “old days” this would be called macro photography – where the subject image is one to ten times larger on the film. -

The Fluorescent Properties of a Stalactite Sample Using the Cary
The fluorescent properties of a stalactite sample using the Agilent Cary Eclipse fiber-optic probe accessory Application Note Author Daren Fyfe PhD Introduction Agilent Technologies The fluorescent properties of secondary carbonate cave deposits Mulgrave, Victoria 3170, (speleothems) are related to the environmental conditions under which they Australia form (for example, soil type, climate and vegetation, and formation of metal ion complexes).1 Speleothem fluorescence is derived from organic acids (humic and fulvic) that precipitate with speleothem calcite after passing though surface layers in rainwater. Using non-destructive fiber-optic technology, the fluorescent properties of these speleothems can be investigated in order to further understand palaeoenvironmental trends. The Agilent Cary Eclipse fiber-optic probe accessory takes light to the sample via an optical light guide. This allows the investigation of the fluorescent properties of samples that cannot be analyzed using more traditional means such as a cuvette or microplate reader2, which are subject to size restrictions or complicated handling requirements. The present study aimed to examine the fluorescent properties of the surface of a cross-sectioned speleothem (stalactite) sample using a Cary Eclipse equipped with fiber-optic coupler and probe. Materials and methods Using the solid sample tip, the probe tip was positioned (For part numbers please see Reference 5) at 45° to the surface of the cross-sectioned stalactite sample using a retort stand and clamp. The solid Equipment sample tip was flush with the surface of the stalactite. Agilent Cary Eclipse fluorescence Using the ‘Scan’ software in ‘3D Mode’, contour plots spectrophotometer of excitation versus emission were collected under Fiber optic coupler ambient laboratory lighting conditions, as a function of distance along the stalactite. -

Introduction to Measurement in the Physics Laboratory
University of Cape Town Department of Physics Introduction to Measurement in the Physics Laboratory A probabilistic approach Version 3.3 2005 Introduction to Measurement in the Physics Laboratory A probabilistic approach Andy Buffler and Saalih Allie Department of Physics, University of Cape Town, South Africa Fred Lubben and Bob Campbell Science Education Group, Department of Educational Studies, University of York, UK To the student As a science, engineering or medical graduate, it will be assumed by your future employer that you have certain skills. These will include problem solving skills, the ability to engage with apparatus that you may not have seen before, the ability to plan and execute an experiment or some type of investigation, the ability to collect, analyse and interpret data and very importantly the ability to communicate and present your findings either orally or in the form of a written report. The contents of this book may be viewed as a complementary course to the practicals that you will undertake in the laboratory as well as a reference manual. As certain skills become necessary in the laboratory, you will have the opportunity to develop these skills using the examples and doing the exercises in this manual. It is thus intended that, (a) during your laboratory course, you will work through the exercises and examples in this manual at the appropriate stage, and (b) this book be used as a reference handbook when you do practical work in the laboratory and then write up your experience in the form of a report. The tasks in this book have been designed to assist you in developing these skills. -
A Modified Device for Rapid Selection of Soil and Water Nematodes from Mixed Suspension
Nematol. medit. (1976), 4: 245-247. I Section of Plant Pathology and Nematology, Department of Botany, Aligarh Muslim University, Aligarh-202001, India A MODIFIED DEVICE FOR RAPID SELECTION OF SOIL AND WATER NEMATODES FROM MIXED SUSPENSION by M.M. ALAM An earlier device (Alam, 1975) for selectively picking up large number of soil or fresh water nematodes was modified and appears to be an improvement over similar devices (Minteer, 1965; Shukla et aI., 1971; Khan et al., 1972) because of its speed and semplicity. The entire apparatus can be easily assembled in any laboratory and does not require any specialised components. Assembley and opera tion details are as follows: Construction details: Two L-shaped glass tubes (0.5 cm dia meter) of 4 and 5 cm lengths were inserted into the neck of a sepa rating funnel 'D' (l00 ml capacity) with the help of an air tight rubber stopper. One of the L-shaped tubes (5 cm length) was con nected through a rubber tubing (75 cm length, 0.5 cm diameter) to anoter glass tube' E' (15 cm length, 0.7 cm diameter) which was provided with a fine tip (7 cm length). The other L-shaped tube (4 cm length) was connected through a rubber tubing (0.5 cm diameter) of desirable length, to an aspirator' B ' (syn. filter pump) which was attached to a water tap' A'. The separating funnel was supported by a retort stand ' C' (Fig. 1). Operation: Before use, the stopper of the separating funnel , D' was closed and then the water tap 'A' was opened to start suction of air into the aspirator' B' resulting in a partial vacuum in the separating funnel' D '.
