Life Is in the Blood
It takes about 60 seconds for all the blood in your body to complete its journey. It travels from your heart to your extremities and returns, there and back again. Blood moves with the rapid current of the great arterial rivers and through the smallest capillary creeks. William Harvey first noticed circulation (1628) through the heart into arteries and veins; however, he could not see how they connected since he did not have a microscope. The man who first described this was Anton van Leeuwenhoek about 46 years later (1674). Then, J. J. Lister and Thomas Hodgkin described the rouleaux formation or stacking of RBCs through a capillary bed. All of these men mentioned above were committed Christians.
Three hundred years ago (1719), Leeuwenhoek was providing his most detailed account of red corpuscles and capillary circulation. He also provided an accurate measurement of 0.003 inches (actual: 6.2–8.2 µm) for human blood cells and described many different types in animal cells. This was about 45 years after he first described them as a young man (1674).
The human body produces two million blood cells deep in its bone marrow per second and pumps 1500–2000 gallons per day. Once formed, those red blood cells (RBCs) move into the bloodstream with white blood cells and platelets, all circulating through 60,000 miles of arteries, veins, and capillaries in the human body. Leeuwenhoek described the connections between arteries and veins as capillaries and demonstrated what Harvey could only postulate. BLOOD REVEALS MUCH ABOUT THE MAJESTY OF OUR CREATOR AND MASTER CRAFTSMAN, IRREDUCIBLE COMPLEXITY, AND THE HEALTH OR DISEASE STATE OF THE HUMAN BODY.
Knowledge of the blood and circulatory system gives us insight into spiritual, biological, and clinical applications. Blood reveals much about the majesty of our Creator and Master Craftsman, irreducible complexity, and the health or disease state of the human body. Capillaries are the smallest blood vessels through which blood cells can move through in single file. This blood vessel network knitted with lymphatic capillaries shows an interwoven complexity, thus revealing the fearfully and wonderfully made design of our body (Gillen, 2009). In this article, we also show a biblical worldview and notable Christians who expounded the biblical concept that “Life is in the Blood.” For the life of the flesh is in the blood. (Leviticus 17:11
Our Impressive Immune System: More Than a Defense
Most likely the immune system was put into place in the original human body design. We know from Exodus 20:11 and other verses that God completed His work of creation in six days. Therefore, the human body and its functional parts, including the components of the immune system, must have been part of the original creation. God said that all He had made was very good (Genesis 1:31). Since there were no pathogens (germs), parasites, or diseases prior the Edenic Fall and subsequent Curse, the immune system may have functioned differently in that world unmarred by sin and death.
The immune system serves more than just to “defend” against disease. The immune system was designed to interact with microbes and cleanse the body of aged, dying, dead red blood cells and bacteria even in the Pre-Fall World. There are toll-like receptors in the immune system that have “sensory” function, as well as defense functions in animals and humans. The immune system in Peyer’s Patches in the GI tract assists the normal development of the intestine and regulates the normal microbiome. Consider a sheep dog designed to positively interact with sheep (herd them); they only “defend” with teeth when a predator (e.g. a wolf) approaches. The immune system in a pre-Fall world (Gillen and Sherwin 2013) worked to positively assist body development (as will be discussed); in the post-Fall world, they also defend against pathogens. This is how most creation biologists view the immune system.
Immunology is that branch of biology that involves studying how the body is designed to protect itself from agents of disease called pathogens. The word immune comes from the Latin root word that means “freedom or protection from taxes or burdens.” This amazing system battles disease in a manner that is so complex and intricate that the most gifted imagination could not envision such incredible functions. In today’s world (post-Fall), the primary role of our immune system is to recognize pathogens and parasites, then to destroy them. Three main methods of destruction include baths of caustic digestive enzymes that cause rapid perforation with submicroscopic holes, overwhelming organisms with sticky proteins, and lastly by ingestion by macrophages (amoeba-like cells). In addition, the immune system is designed to prevent the proliferation of mutant cells, such as various cancers. When this system malfunctions or when a boundary is breached, it can result in localized or systemic infections, or worse, death
A multiplexed single electron transistor for application in scalable solid-state quantum computing
Single Electron Transistors (SETs) are nanoscale electrometers of
unprecedented sensitivity, and as such have been proposed as read-out devices
in a number of quantum computer architectures. We show that the functionality
of a standard SET can be multiplexed so as to operate as both read-out device
and control gate for a solid-state qubit. Multiplexing in this way may be
critical in lowering overall gate densities in scalable quantum computer
architectures.Comment: 3 pages 3 figure
Church Marketing: Promoting the Church Using Modern Methods
Marketing is a part of nearly every aspect of business. Without marketing, businesses would have very little means of communication. It is an essential part of promotion and growth. The same is true within the church. Churches often stray from advertising for a variety of reasons, but marketing and promotion can be a very effective way of fulfilling the Great Commission in a new, unique, and modern way. \u27 This thesis will illustrate important steps in developing a communications plan for the marketing of local church. Research was done on existing marketing plans in both the business and church setting. The end goal of this thesis is to show that marketing can benefit the church and is truly Biblical at its very core
Spacelab mission dependent training parametric resource requirements study
Training flows were developed for typical missions, resource relationships analyzed, and scheduling optimization algorithms defined. Parametric analyses were performed to study the effect of potential changes in mission model, mission complexity and training time required on the resource quantities required to support training of payload or mission specialists. Typical results of these analyses are presented both in graphic and tabular form
