How to Collect Forensic Science Fingerprints Using Latent Print Powders at the Crime Scene
Latent Fingerprint development has challenged crime scene investigators for decades. Collecting forensic science fingerprints has evolved from the early use of lampblack (soot) to complex formulations that incorporate some sophisticated chemistry. This article will examine the use of latent fingerprint powders-included will be the whys and wherefores of latent powder formulations.Latent print powders are divided among several different categories-each category having very specific uses. The first consideration for the crime scene investigator to examine is the type of surface expected to yield latent prints:Porous Surfaces: This includes paper, cardboard and raw wood. Unless latent prints are suspected to be reasonably fresh, latent print powders are not of much use on non-porous surfaces, since the moisture content disperses into the substrate and ridge detail is lost.Non-Porous Surfaces: This is where latent powders most often come into play. The problem is, however, that all non-porous surfaces have different characteristics that require a specific formula of latent powder.Latent Powder Formulations: Latent powders fall into the following categories:1. Standard-Oxide Powders: This category covers formulations that have been in use for nearly a century. Included are Black, White, Gray and Red2. Metallic Powders: These powders are formulated using actual, finely ground metal particles like aluminum, copper and bronze.3. Magnetic Powders: All magnetic powders have, as their main ingredient, iron or iron oxide-a material that is easily magnetized.4. Fluorescent Powders: Fluorescent powders have a special use-they are ideal when applied to multicolored backgrounds. Once it is apparent that latents are present after development, the CSI dims the light available and uses an ultraviolet lamp or alternate light sources (blue, green or red) to produce fluorescence. These developed latents actually “glow” in the dark.5. Combination Powders: A problem often encountered in latent print development is how to view a latent print on a dark surface when using a light colored powder or vice versa. Another problem is the difference between smooth surfaces and surfaces made of highly polished metals such as silver plated or chrome plated surfaces. This one powder combines the properties of an oxide and a metallic powder, and one formula may be used on wither dark or light backgrounds.As mentioned above-all non-porous surfaces are not alike when it comes to choosing a latent print powder. For example: An Automobile Body-Standard Oxide Powders may be used on the painted surfaces, but it is necessary to use a metallic powder on chrome-plated areas like bumpers and trim.Magnetic powders were invented back in the early 1970s and they enjoy a prominent place in the crime scene kit. Magnetic powders may be used on practically any surface EXCEPT those surfaces containing iron or steel. All of the other powders are applied using a brush-either animal hair (camel or squirrel) or synthetic materials like fiberglass or carbon fiber. Feather dusters are also used mostly as a cleanup tool after a regular brush is used to develop the print. The feather duster will remove excess powder in the case of over development. Magnetic powers are applied using a magnetic wand, and magnetic powders cling to the magnet actually forming a “brush” that touches the surface-and not bristles from a brush.Fluorescent powders have also been available for several decades. They all contain a pigment that emits light at other than white light frequencies. This fluorescence is especially useful on multi-colored backgrounds like beverage cans, potato chip bags and candy wrappers. Under low light conditions these powders become fluorescent when exposed to longwave UV light (black light). Many fluorescent powders are also visible under alternate light sources, but the fluorescence isn’t visible since the light from the source overpowers the weak glow of fluorescence. To compensate for this, the crime scene investigator uses a filter-depending on the color of the alternate light source (ALS)–which is mostly blue, green or red. An orange or yellow filter blocks blue and green visible light, and a red filter is used for red ALS.

Commercial Real Estate Loan Basics For Small Business Owners
The most challenging aspect in commercial borrowers reacquainting themselves with the “basics” for commercial mortgage loans is likely to be the need to not only focus on the “old basics” but also on numerous “new basics” created by a massive shift in commercial loan services. There have been surprising difficulties and changes for small business financing, and this is particularly illustrated by the current commercial banking climate for commercial mortgages. Because the issues currently impacting commercial real estate loans are so widespread and effecting business borrowers everywhere, it is appropriate for business owners to “get back to basics” before they finalize any new business loans.The outcome that effective commercial real estate financing is becoming harder to find is the biggest net result of the changes and challenges involving commercial mortgages. This observation applies equally to new commercial loans for buying a business and commercial refinancing efforts. Very few commercial lenders are providing a candid assessment of their inability to provide commercial mortgage financing for a wide variety of small businesses, and this makes the challenge almost insurmountable.The need for small business owners to be prepared for an extremely difficult commercial lending environment is an intentional emphasis in this discussion. Obtaining commercial mortgages can no longer be taken for granted by small businesses because of the recent ineffectiveness that prevails with commercial banking. Large corporations continue to have more leverage and resources for dealing with their banks. In a mirror image of that situation, small business borrowers are increasingly likely to have less resources and leverage when negotiating with any bank.Fewer banks providing this kind of financing to small businesses is one inescapable “new basic” for commercial real estate loans. It will frequently be even more difficult to secure a commercial mortgage from a new and unfamiliar lender if the current bank for a business is not willing to help. Nevertheless that is a likely funding scenario that currently confronts business borrowers everywhere. A particularly growing (and annoying) trend as noted above is that when banks have reduced their commercial loan activities, they are not generally being straightforward in telling prospective commercial borrowers. Banks are more intertwined than ever with political influences after a large number of them received government bailouts that helped to keep them operating. Very few banks have actually followed through on the promise to return to a “normal” level of lending once they received bailout funding.A reduced amount of leverage for most small business loans is another “new basic” that seems likely to prevail. Needing larger down payments to buy a business will be one result for borrowers. Especially when combined with decreasing commercial real estate values currently being experienced on a widespread basis, commercial debt refinancing will be more difficult because of the reduced leverage.We previously published a companion piece describing the need to get back to basics with working capital financing. In terms of the growing challenges with commercial refinancing, the points made in that article are directly relevant to this discussion. Our primary point is that any current effort to refinance a business loan is likely to be much more difficult than expected, and a small business owner might experience obstacles in getting needed cash by refinancing an existing commercial mortgage loan even when they have substantial equity. When commercial real estate refinancing cannot be obtained, commercial borrowers should consider a working capital loan as a “Plan B” solution.
Mind Body Medicine
Everything about this physical life that you lead is experienced from the standpoint of your physical body. When your body is in a state of health, it reflects out into all aspects of your mind. What is overlooked in society today is that the reverse is also true. When your mind is in a state of health, it reflects its self out into all aspects of your body. It is very easy to fall into the path of shortsightedness and say for example that an illness comes from a specific virus. It is easy to say you know it comes from this specific virus because you can see it visibly with a microscope hacking into cells. This however is the same as telling the story that the light which illuminates a room comes from a light bulb. The story of where light it’s self actually comes from can be traced much further than the light bulb. It is a much longer story, just as illness is a much longer story than what is obvious and visible, which we often call the “cause”.Many people assume that there are physical conditions that dictate by default how your life will end up. Conditions determined by things such as DNA. The problem with this mode of thinking is that DNA is activated and told how to express it’s self by the mind (human consciousness). Mind (thought) is the bridge between spirit and body. You find harmony with your spirit using your thoughts and you use thoughts to create harmony in and of your body. Your entire body, originated as a thought. Therefore, when your thoughts change to match an energetic vibration which is negative, it is as good as re writing the blueprint of your body. This negative change then manifests as illness. Chronic disease is in fact caused by chronic thoughts such as those of fear, stress, guilt, resentment, overwhelm or hate. If there is no weakness present in the pre- manifested vibrations of thought, there is nowhere for illness to occur, there is nowhere for traumatic injury to occur, there is no way for a virus or bacteria to effect you, and your genetic predispositions towards a particular disease will be dormant.It is for this reason that the modality of mind medicine (thought) could quite possibly be the most important part of healing. No matter how much you do on the physical level to change circumstances that have already manifested, they will continue to manifest again and again if the thoughts you are habitually thinking remain the same. There is nothing that is physical that is truly static. No matter what the statistics and odds tell you, anything that has manifested in the physical in the first place, has the ability to change. Nothing exists in this physical world that with or without certain changes being made, has a decided outcome. To put yourself physically in a chronic state of health, all you have to do is make thoughts which hold a positive energetic vibration, (thoughts that feel good to think) the thoughts which are habitual and chronic for you to think.
