Introduction
Claude Bernard was a French Physiologist who was best known for his works and discoveries during his lifetime in the field of digestive processes, the liver and the regulation of the supply of the blood though the vasomotor nerves. The most renowned and important discovery of Bernard was related to use of the secretions of the pancreatic tissues to break down the molecules of fat into smaller particles so as to aid the digestion process and the other specific discovery was that the principle process of digestion does not take place in the stomach rather it takes place in the small intestine. His next discovery unveiled the ability of the liver to split the reserves of the glycogen energy into sugar particles so as to use them as a quick source of energy for the body and to maintain the levels of the sugar in the body. Finally, Bernard discovered the control of the vasomotor nerves on the blood vessels, and how it responds to the changes in the temperatures while operating in an environment. With this the Bernard was able to advance his work on blood vessels and tried to understand the ability of the body to constantly maintain the internal temperature. This led him to formulate the ideas in relation to the constancy of the internal environment of the body. In the 19th century his concept of constancy of the internal environment (milieu interieur) was officially presented.
In this paper, we are going to analyze the statement made by Claude Bernard in 19th century- “The constancy of the internal environment is the condition for a free and independent life.” and we will relate this statement to the life processes and the other important...

...Chapter5: Physical Development in Infancy & Toddlerhood GURE 5.21 Acting on the environment plays a major role in perceptual differentiation Crawling and walking change the way babies perceive a sloping surface. The newly crawling infant on the left plunges headlong down the slope. He has not yet learned that it affords the possibility of falling. The toddler on the right, who has been walking for more than a month, approaches the slope cautiously. Experience in trying to remain upright but frequently tumbling over has made him more aware of the consequences of his movements. He perceives the incline differently than he did at a younger age. Summary Body Growth Describe major changes in body size, proportions, muscle–fat makeup, and skeletal growth over the first two years. ■ Height and weight gains are greater during the first two years than at any other time after birth. Body fat is laid down quickly during the first nine months, whereas muscle development is slow and gradual. Parts of the body grow at different rates, following the cephalocaudal and proximodistal trends, resulting in changing body proportions. ■ Skeletal age, a measure based on the number of epiphyses and the extent to which they are fused, is the best way to estimate the child’s overall physical maturity. At birth, the bones of an infant’s skull are separated by six gaps, or fontanels, which permit the skull to expand as the brain grows. Brain Development Describe brain development during......

Gender Identity

...Internal and External Factors Influencing the Development of Gender Identity Lanita Doub Liberty University COUN 502-Human Growth & Development Laura Rolen August 11, 2012 Internal and External Factors Influencing the Development of Gender Identity Gender identity is defined as "the perception of oneself as male or female", ( Feldman, 2011). Gender is established by the time a child reaches his or her preschool years. "By the age of two, children consistently label themselves and those around them as male or female" (Feldman, 2011). Preschoolers are very rigid in their beliefs about gender-appropriate behavior. These beliefs become more pronounced by the age of five years. By age seven years the beliefs are still there, although less rigid. Preschooler's ideas of stereotypical behavior are compared to those of traditional adults. Preschoolers develop a gender schema, "a cognitive framework that organizes information relevant to gender"(Feldman, 2011). For example, a preschool boy may refuse to wear makeup in a school play because he knows that makeup is for girls only. In 1966, Lawrence Kohlberg proposed a cognitive-developmental theory, which explains the rigidity of preschoolers as their understanding of gender, and gender appropriate behavior (Feldman, 2011). Shuvo Ghosh states that the development of gender identity "clearly begins in the intrauterine stage". He attributes this to hormone......

Psy/345 Annotated Bibliography

...pq-origsite=summon&seq=1#page_scan_tab_contents Attention often plays a crucial role in motion perception. For example, when a stimulus contains two components moving in opposite directions, attentive tracking of either one can reveal its motion independently of the other. Many neurons in primary visual cortex are sensitive to the direction of motion and attention might act by selecting one or the other of these low-level motion responses. Experiments have demonstrated that the perception of motion during attentive tracking can arise independently of low-level motion responses and may be derived from the internal signals that move the focus of attention. What the studies found in this experiment is tracking of spatial features depends on identifying form boundaries, and it appears that the form signal from luminance is especially susceptible to masking by color. This might be expected because any object traveling through a shadowed environment will have many luminance boundaries drifting across it that are unrelated to the object and need to be discounted, whereas color boundaries are more reliably tied to object borders Cues for depth perception.

W. Edwards Deming- a Total Quality Pioneer

...• How Deming’s use of quality and its elements made him successful. • Why the elements of quality are useful in today’s environment. • What I foresee about the future of quality Definition of quality According to Qualitydigest.com, “Quality is the ongoing process of building and sustaining relationships by assessing, anticipating, and fulfilling stated and implied needs.” In a nutshell it is providing the customer with the quality that was promised. Every thing purchased has a specific task it is supposed to achieve. If we buy whitening toothpaste, we expect it to whiten our teeth by the time we finish the tube. If this doesn’t happen then we would probably think that the quality is not good because it didn’t accomplish what it stated on the packaging. Elements of Quality This consists of the components of doing business. It means strategizing, focusing on the customer, how businesses should be obsessing over quality, and scientific approaches to measure improvements. Businesses should commit long term to change and continued improvement. Education and training can help employees with teamwork and the ability to work more efficiently. It is a combination of these tasks that can improve quality. Deming’s 14 points Deming’s 14 points inspired changes in businesses that wanted to compete successfully in a competitive environment.

...nanoT - VaryCell TM Micro stage for time lapse imaging and temperature mediated cellular studies. Cells derived from mammals have an optimum in vitro growth rate between 36°C to 37°C as their in vivo physiological temperature ranges between 36.5–37.5 °C (97.7–99.5 °F) in a normal individual. Homeostasis process maintains the constancy of the organism’s internal environment in response to changes in external conditions. Thermoregulation is part of the aforementioned process as controlled by the organism’s circadian rhythm. Figure 1: Diurnal temperature variation chart However there are cell types which have optimum growth at different to that of human cell types i.e. insect, avian, amphibians and cold water fish cells. Ectotherms or cold blooded animal cells can grow within a temperature range between 15°C and 26°C. Insect cells has an optimal growth at 27°C and can grow between 27°C and 30°C. Avian cells has an optimal growth at 38.5°C, however they can be cultured at temperature ranging between 37°C to 38°C. All the above cell types can be cultured in vitro at their optimal growth condition including biological gas flow using nanoT - VaryCellTM .
