Every believer needs help to develop a relationship with the God of Heaven. One-on-one discipleship provides believers with the needed atmosphere of love, care, and patience, as they are personally mentored by more mature believers in the scriptures. These lessons are meant to help believers of all maturity levels grow in the faith, so that they can stand against Satan's attacks and live victoriously for Jesus Christ (Matthew 5:13-16). This book is the second in a series of six, which covers how to delight in God's Word. It is divided into five lessons, which are as follows: 1. The Sufficiency of Scripture 2. The Preservation of God's Word 3. Faith Comes by Hearing 4. Responding to the Word of God 5. How to Take Notes Each lesson comes with a set of objectives, interactive questions and answers, and additional homework to help the student study through the scriptures at a structured pace.

Due to a combination of advances in technology, government legislation, and market forces, the LED lighting market is set to explode. This can be looked at in a number of different lights, from the rather small (home lighting is about to be totally gadget-ified), to the large (about 4 billion light bulbs in the US are going to be replaced, many of them with LED bulbs), to the world-changing (for the first time in history man is providing light for himself without the use of some form of fire). This book focuses on the first of those three: it's a practical, actionable explainer for LED lighting, aimed at the normal, household replacement bulb, but many of the same concepts apply to other bulb designs (MR16, PAR) and lighting scenarios.

LED bulbs are available, and while they will be changing greatly over the next few years, the core concepts will remain the same. This provides consumers (and, let's face it, geeks) with two interesting questions -- what to do now and what do they need to know about the future. The book tackles both of those, from explaining the parts of an LED bulb, to talking through some of the interesting challenges manufacturers face, to discussing implications for the future of solid state lighting. It's a mix of the practical and an examination of the LED bulb as a gadget, the way you'd look at a mobile phone or laptop.


Walking Home To Rosie Lee

RRP $12.99

Young Gabe's is a story of heartache and jubilation. He's a child slave freed after the Civil War. He sets off to reunite himself with his mother who was sold before the war's end. "Come morning, the folks take to the road again, singing songs, telling stories, and dream-talking of the lives they're gonna live in freedom. And I follow, keeping my eyes open for my mama. Days pass into weeks, and one gray evening as Mr. Dark laid down his coat, I see a woman with a yellow scarf 'round her neck as bright as a star. I run up to grab her hand, saying, Mama?" Gabe's odyssey in search of his mother has an epic American quality, and Keith Shepherd's illustrations—influenced deeply by the narrative work of Thomas Hart Benton—fervently portray the struggle in Gabe's heroic quest.

Selected as a 2012 Skipping Stones Honor Book and for the 2012 IRA Teacher's Choices Reading List.

A. LaFaye hopes Walking Home to Rosie Lee will honor all those African American families who struggled to reunite at the end of the Civil War and will pay her respects to those who banded together through the long struggle for freedom. She is the author of the Scott O'Dell Award-winning novel Worth and lives in Tennessee with her daughter Adia.

Keith Shepherd is a painter, graphic designer, and educator working out of Kansas City, MO. His painting "Sunday Best" is part of the Negro Leagues Baseball Museum's permanent collection. He describes his work as being "motivated by family, religion, history, and music."



Protein Moonlighting In Biology And Medicine

Of the two major products of the gene (proteins and microRNAs) it is the protein that is the functional unit of biology. A combinatorial association of 20 amino acids in linear chains of up to 30,000 residues generates, or can generate in theory, many more proteins than there are stars in our universe. The protein molecule can be chemically active, in the form of an enzyme, whose catalytic effect can speed up chemical reactions by a thousand- to a million-fold. It can be a structural component acting as a tissue support or allowing the transmission of force. It can function as a binding protein, acting to transport other molecules or atoms or act as a receptor binding its ligand to transmit information into the cell. 

Proteins are vitally important for life, and this is clearly indicated by the number of genetic diseases whose symptoms are due to altered protein sequences. The classic example of this is sickle cell disease, due to a single amino acid substitution in haemoglobin, resulting in a protein that aggregates when deoxygenated causing massive structural changes in circulating erythrocytes. The function of proteins can be explained by the evolution in the protein of a specific interaction between amino acids to generate what is termed an active site.

Not stated in the central dogma, but generally taken for granted, was that each protein product of the gene had one single biological function. This one-protein-one-function hypothesis was falsified by the first example of a protein exhibiting two functions. In addition, the transparency of a protein is not really a functional property but is a physical property of these molecules. So it was not until the 1990s that additional examples of proteins exhibiting more than one function were identified and another term to describe this phenomenon was introduced. Connie Jeffery, from the University of Chicago, introduced the term Protein Moonlighting in 1999 for the phenomenon of proteins having more than one unique biological function. Since the introduction of the term, protein moonlighting, a slow trickle of serendipitous discoveries of moonlighting proteins has been made such that at the time of writing over one hundred examples of such proteins have been made.  While this is a small number of examples, it is possibly only the tip of the iceberg that is the proportion of moonlighting proteins in biology.

Protein moonlighting has only come to prominence in the last 15 years. Although only a small number of protein families have been found to moonlight, the consequences of such additional activities are already  known to be of significance in both biological and pathological/medical terms. Moonlighting proteins are known to be involved in human diseases such as cancer and there is rapidly emerging evidence for a major role for protein moonlighting in the infectious diseases. Protein moonlighting has potential consequences for various branches of biology.  The most obvious is the field of protein evolution. In moonlighting proteins not one, but two or more, active sites have evolved. This calls into question our current models of protein evolution and generates a range of questions as to the evolutionary mechanisms involved. Further, as it is emerging that moonlighting protein homologues do not necessarily share particular moonlighting activities the level of evolutionary complexity in generating biologically active sites seems much greater than was previously thought. 

Another area impacted by protein moonlighting is the field of systems biology. The complexity of cellular systems with their multitudes of interacting networks of proteins is currently predicated on each protein having one function. However, if a sizable proportion of proteins moonlight then this will dramatically increase cellular network complexity.

This book brings together a biochemist (Henderson) an evolutionary biologist (Fares) and a protein bioinformaticist (Martin) who have had a long-term interest in protein moonlighting. The discussion covers all aspects of the phenomenon of protein moonlighting from its evolution to structural biology and on the the biological and medical consequences of its occurrence. The book should be of interest to the widest range of biomedical scientists.
