Blood in Crime Scene Investigation
At the scene of a violent crime, the examining officer will likely discover blood and evidence of other bodily fluids. These can tell a lot about what occurred, not only regarding details of how the crime was committed, but also about the people involved.
These days, nearly everybody knows their blood type, and whether it is A, B, AB, or 0, and Rhesus negative or positive. This division of blood into types was first made by Austrian physiologist Karl Landsteiner at the end of the 19th century. In his experiments, he took small amounts of blood and separated the red cells from the liquid, called serum. He did this by spinning the blood at high speed in a centrifuge. Then he took the serum and added red cells from different people. They acted in two different ways: either the cells mixed with the serum, or they clumped together (clotted), (”agglutinated”).
A number of attempts at blood transfusion had been made in the past, but this observation explained for the first time why a great proportion had failed. If introduced blood was not of exactly the same type as that in the body, it produced the clumping of red cells, and the patient died. Quick tests of blood samples to discover whether agglutination will happen is now made before a transfusion is performed.
DIVIDING BLOOD INTO GROUPS
Red blood cells carry substances called antigens. Antigens help make antibodies which fight infection and disease. Landsteiner suggested that his experiment showed the presence of two specific antigens, which he labelled A and B. The discovery of these antigens enabled him to divide human blood into four basic groups:
Group A: antigen A present; antigen B absent
Group B: antigen A absent; antigen B present
Group AB: both antigens A and B present
Group 0: both antigens absent
The specific blood group of a person depends on the genetic inheritance from both parents. Known as ABO typing, it has been used, for example, to identify the biological father in paternity cases. How common each group is can vary from one national population to another. In the United States, for example, the relative proportions of ABO groups are roughly 39 percent A, 13 percent B, 43 percent 0, and 5 percent AB.
In 1927, Landsteiner found two other antigen types, labelling their occurrence as M, N, and MN. In 1940, working in the United States, he and A.S. Wiener discovered the Rhesus factor, named after the Rhesus monkeys they used in their investigations. Since then, other researchers have introduced more than a dozen further group systems. Different proteins and enzymes associated with specific blood groups have also been identified.
WHAT THIS MEANS FOR FORENSICS
The ability to identify blood type is a powerful tool to uncover important evidence in a forensic investigation. If, for example, a victim’s ABO type is O, and bloodstains of this type are discovered on clothing of a suspect whose type is A, there is a possibility that they have come from the victim.
Making use of the many other blood typing systems now available, this probability can be increased greatly. If blood of type O occurs in 43 percent of the population, the substance haptoglobin-2 in 36% of these, and the enzyme PGM-2 in 5%, then the probability of an individual having these three blood types together is 43 x 36 x 5 = 7,740 in 1 million. In other words, around 8 people in every thousand will have this specific type of blood. It’s still not enough to obtain a conviction on this evidence alone, but it can help to narrow the number of suspects.
In 1925, another valuable discovery was made. Around 80 percent of humans are ’secretors’. This means their saliva, urine, perspiration, and semen contain the same substances as their blood, and are able to be used for typing in a similar way. In 1940, two British researchers discovered that it was possible to distinguish between female and male body cells, especially the white blood cells and those of the lining of the mouth. Blood typing is now so precise that recently one scientist showed that he could distinguish between the blood of his twin daughters, who were genetically identical, because one had suffered from chicken pox and the other hadn’t.
SPLASHES OF BLOOD
At the scene of a violent homicidal attack, blood may be present in considerable quantities. Not only will it be found on the victim, but also on the weapon and the surroundings. Indoors, the floors, walls, and even the ceilings may be splashed. Careful observation of these bloodstains can provide valuable clues about what took place. Bloodstains and splashes are classified into six basic types.
Round drops are found on horizontal surfaces; depending on the height from which they fell, they can spray out into a starlike shape. Splashes of blood are shaped like an exclamation mark; they show that blood has flown through the air and hit a surface at an angle. While a victim is still alive, spurts of blood result from the pumping action of the heart. A major artery can spray blood a considerable distance.
Pools of blood form around the body of the bleeding person. If there is more than one pool, he either dragged himself, or was moved, from one spot to another before dying. Smears are likely also found if this happens. Trails are left when a bloody body is moved. There will be drops if the body was carried, and smears if it was dragged.

Law firm marketing: Making the most of what you’ve got!
Whether the marketing strategy for your law company is based on online marketing, niche marketing to particular industries, traditional advertising, or just retaining and growing wallet share of your stable of clients, you’ll need to generate content.
Content is the lifeblood of legal marketing, and without it you might just as well not have a law firm marketing plan. However, producing content requires hard work, and you want to make the best of the writing that you manage to produce. Here are some quick ideas to help you use the two most popularly produced types of legal marketing content as effectively as you can.
Law Firm Marketing - Written material (blogs, email alerts, brochures, guides, information sheets)
If you’ve created some quality, interesting material of any of the forms above, you don’t need to just send it out once or print it and let it sit in your reception. You can distribute that content as much as is possible. For every item of written material you produce, consider:
- Have I sent it to as many, relevant, clients as I can?
- Has it been loaded onto my website?
- Have I emailed it direct to referrers, associates and other professionals?
- Have I linked it with a post on Facebook and a tweet on Twitter?
- Has it been sent to media contacts?
- Are others in the company aware of it and could they explain it in detail if a client asks?
- Can I transform it into a different kind of content and distribute in a different form?
Law Firm Marketing - Presentations
Presentations are usually written with a specific reception in mind, or because of a particular request. As a result they are often presented only once then left to stagnate. All of that time involved in preparing it gets just one showing. To get far more benefit from your presentation consider:
- Who else could I present it to?
- How could I let the greatest number of people know about it?
- Have I mentioned it on our website, Facebook, Twitter, and suggested that I present it to others?
- Can I send the presentation in hard copy to people who couldn’t attend the seminar?
- Could I record an audio or video of the presentation and distribute it electronically online or directly?
- Is it viable to write an article or blog discussing topics that arose during the presentation?
- Have I sent additional content to all the people that attended the presentation?
Although these suggestions may feel like additional work at a time when you’ve probably created a dent in your monthly billings with the amount of time you spent preparing the first lot of material, it’s crucial to consider that it is far easier to use a small amount of time at the end to really maximise on the impression you’ve already produced than to produce a completely new piece of legal marketing material.
Maximise the benefits of all the time and effort you put into law firm marketing and you’ll see that the next time you need to create some content you will feel more confident about how effective the results will be.

Sphere: Related ContentRelationship Combatibility Factors
Relationship and Marriage counseling can help you find out how suitable you are.
The two most crucial factors that decide how compatible you are as a couple are:
A similar level of psychological vitality and maturity and a similar ranking of Instinctual Variants.
What are Instinctual Variants?
The 3 Instincts represent the natural energies or drives that are inherently part of us as humans. Our personality is highly engaged with and often dependent on these libidinal, instinctual energies to give it its spark.
Self Preservation Instinct.
People of this Instinctual variant are often with the basic survival needs as they translate into our modern society, for example, money, food, accomodation, health, physical safety and comfort.
Being secure and physically comfortable are essential, and they will tend to bring these supplies with them.
When entering a room, they will tend to notice bad lighting, uncomfortable chairs, the room temperature, when the lunch break will be, and whether they will enjoy the food provided. They also tend to be the most practical in the sense of taking care of pressing necessities of life.
They are the most introverted of the types.
Sexual/ Intimate Instinct.
People of this kind have a strong desire for severity of experience and affection. The forthright riveting gaze is the dead giveaway. When they enter a situation they automatically gravitate toward people they feel magnetized to, as if they are looking for the juice. These people can turn into intimacy addicts, often ignoring pressing obligations or even basic maintenance if they are swept up in something that has captivated them. This gives a expansive exploratory philosophy to life, but can also generate a lack of focus of one’s own goals.
Social Instinct.
People of this variation are focused on their interactions with other people and with the sense of value and esteem they derive from their participation in collective activities. These include occupation, family, hobbies and clubs.
Upon entering a room, these people would immediately be aware of the relationships and subtle politics between the different people and groups. They are subconsciously focused on other people’s reaction to them, particularly about whether they are being accepted or not.
They need to interact with others to feel safe, acknowledged and energised. They tend to love interacting with people, but they avoid intimacy.
They are the most extroverted of the types.
Within each person, one of these Instincts will dominate. In fact the 3 variants can be ordered like the sections of a cake, with the most dominant one at the top. The least powerful one, at the bottom, is termed the blind spot.
These instincts play an essential role in our relationships because people of the same variant tend to share values and understand each other completely, and therefore feel very compatible.
In relationships between 2 different Instinctual types, each will struggle to convert the other.

Sphere: Related ContentThe Importance of Proofing Designs
You’ve concluded it’s time for a new website or design. For most, the first step is to choose the right organization. However, the first thing you need to do is formulate at least a basic concept of what you expect from a finished product. Not only is this step often ignored in the starting phase of project formulation, but also during the creative briefing phase after hiring a design company.
Everyone wants to send off a concept to the professionals and let them take care of it all. If you’re having your car washed, then nothing is really required of you. For design briefs, you need to be more directly involved. Website design and graphic design are two fields where getting yourself involved is necessary to the perfect design for you and your business.
During your first meeting with a website and graphic design company, you should supply them with your estimations and goals. This gives the company with a starting point. This doesn’t mean that you are finished. No one can read your mind. In order to make absolutely certain you get the most optimal design possible, you must take the creative briefing stage extremely.
This is the stage of the assignment where you work one on one with the designers to ensure they fully comprehend what you desire. The more they understand, the faster that can deliver the finished project. It also reduces the number of initial design changes.
The next step before the designer can work on your project is proofing your design. You should never just quickly glimpse the design and give your approval. Look over the design plans as thoroughly as you would any important document. If the design isn’t exactly as you envisioned it and doesn’t provide the features you discussed, now is the time to make changes.
Waiting until the final project is delivered means time consuming revisions for both you and the designer. By involving yourself in both the creative briefing and design proofing stages, you save both time and money. You also get the perfect website or graphic design the first time around. The sooner your project is in place, the sooner your customers and visitors will see it.
You should never take this responsibility lightly. It’s your design, your website. Take the time to ensure the design company you choose fully understands your vision. By communicating your needs, the company is able to provide suggestions. With thorough communication between both parties, the best designs and sites are created.

In some other states of Australia the conveyancing process (the legal process required to transfer ownership of house) can be undertaken by licenced conveyancers. This is not the case in Queensland where conveyancing must be undertaken by a solicitor/lawyer.
