Volume of atoms in unit cell In a simple cubic structure, the atoms occupies at the eight corners. An atom at the corner is equally shared by 8 unit cells. So the contribution of one atom to a unit cell is 1/8.

  2. Nov 24, 2022 · It is a potentiometer that uses an electrode whose potential depends on the amount of H+ ion present in the solution. (It is an example of an ion-selective electrode.) This allows the pH of the solution to be measured throughout the titration. At the endpoint, there will be a sudden change in the measured pH.

    A common misconception about blood in flight is that it has a natural tendency to form a teardrop shape in flight. Through experiments with blood, it has been shown that a drop of blood actually tends to form a sphere in flight. The formation is caused by surface tension, which is what holds the drop together. Surface tension gives fluids a tendenc...

    The area of origin is the three-dimensional space where the blood source was located when the blood began its journey. It is important to remember that bodies tend to be dynamic. Not only can the source of blood be engaged in major movements, but there are also small movements to take into account, such as the elasticity of skin. When a force is ap...

    The string method is one of the oldest techniques for determining an space in which the bloodletting occurred, based on a bloodstain pattern. First, angle of impact and area of convergence needs to be determined. Then, the BP analyst will place their protractor at the blood stain location and project a string at the angle of impact in the direction...

    Bloodstains at a suspected crime scene are typically photographed in three different ways, since each way has its pros and cons when its time to analyze the scene. Photographing the bloodstains is important for several reasons, and one of them is that a BP analyst might be unable to attend the scene personally and will have to relay on documentatio...

    Doctor Piotrowski

    One of the earliest scientific studies of bloodstain patterns was made by Dr. Eduard Piotrowski of the University of Kraków in 1895. Even long before this study, bloodstain pattern analysis was sometimes used by law enforcement, but without much formal science to back it up. Dr. Piotrowski’s paper dealt with the formation, form, direction, and spreading of blood stains after blunt trauma to the head.

    LeMoyne Snyder

    LeMoyne Snyder’s book “Homocide Investigation”, published in 1941, was widely used by forensic analysts of that era. It mentions bloodstain analysis, but only briefly. Examples of facts pointed out in the book are that bloodstains tend to fall in certain patterns based on the motion of an attacker and the victim, and that blood dries at a relatively predictable rate.

    The International Association of Bloodstain Pattern Analysts

    The International Association of Bloodstain Pattern Analysts (IABPA) was formed in 1983 in Corning, New York State, USA, under the guidance of Herbert MacDonell. Herbert MacDonell was the researcher who published the first modern treatise on bloodstain analysis: “Flight Characteristics and Stain Patterns of Human Blood” in 1971. The first formal bloodstain training course was given by him in Jackson, Mississippi, in 1973. IABPA was founded by a group of blood stain analysts who wished to furt...

    A report released by the United States non-profit organization The National Academy of Sciences in 2009 highlighted several cases where blood splatter analysts had overstated their qualifications. The report also questions the reliability of BPA methods. Just as with many other forms of forensic evidence, bloodstain pattern analysis used in the leg...
