Pengaruh pelarut isoamil alkohol dan isobutanol terhadap reaksi esterifikasi asam lemak minyak sawit dengan sukrosa menggunakan lipase candida rugosa E.C.3.1.1.3 terimobilisasi pada nanopartikel Fe3O4 kitosan = The effect of isoamyl alcohol and isobutanol in esterification between palm oil fatty acid and sucrose using immobilized candida rugosa lipase E.C.3.1.1.3 on Fe3O4 chitosan nanoparticles
"Ester asam lemak kelapa sawit sukrosa dapat disintesis melalui reaksi esterifikasi enzimatis menggunakan lipase Candida rugosa. Pada penelitian ini, digunakan pelarut isoamil alkohol dan isobutanol. Reaksi esterifikasi menggunakan lipase Candida rugosa E.C.3.1.1.3 bebas maupun terimobilisasi pada nanopartikel Fe3O4-kitosan. Imobilisasi lipase Candida rugosa pada nanopartikel Fe3O4-kitosan menggunakan metode ikat silang dengan glutaraldehida sebagai agen pengikat silang. Terhadap hasil imobilisasi dilakukan uji aktivitas dan persen loading. Pada peggunaan enzim 200 ppm didapatkan persen loading imobilisasi lipase sebesar 31,4% dengan aktivitas hidrolisis lipase terimobilisasi sebesar 3,470 U/mL, aktivitas spesifik 0,991 U/mg, serta efisiensi imobilisasi sebesar 23,25 %. Sementara itu, pada penggunaan 350 ppm enzim didapatkan persen loading imobilisasi lipase sebesar 64,4 % dengan aktivitas hidrolisis lipase terimobilisasi sebesar 2,245 U/mL, aktivitas spesifik 0,64 U/mg, serta efisiensi imobilisasi sebesar 14,88%. Kondisi rasio substrat optimum diperoleh pada rasio 1 : 90 (sukrosa : asam lemak). Hasil uji emulsifer menunjukkan hasil positif. Pelarut terbaik untuk sintesis ester -sukrosa dengan lipase terimobilisasi adalah isobutanol.
Palm oil fatty acid-sucrose can be synthesized via enzymatic esterification using Candida rugosa lipase. The solvents used in this study were isoamyl alcohol and isobutanol. Esterification reaction was carried out enzymatically using free lipase and immobilized Candida rugosa lipase E.C. 3.1.1.3 on Fe3O4-chitosan nanoparticles. The immobilized lipase were examined to determine the loading percentage and the hydrolytic activity. The loading percentage obtained while using 200 ppm lipase for immobilization was 31,4%, with hydrolytic activity of immobilized lipase was 3,47 U/mL, the specific activity of 0,99 U/mg and the immobilization efficiency of 23,25%. Meanwhile by using 350 ppm lipase the loading percentage obtained was 64,4% with hydrolytic activity of 2,25 U/mL, the specific activity of 0,64 U/mg and the immobilization efficiency of 14,8 %. From this optimization study of esterification, the highest conversion came from sugar and fatty acid ratio 1 : 90. The esterification product gave positive test on emulsifier test. The best solvent to synthesize ester-sucrose using immobilized lipase is isobutanol."

Understanding evolution
"Current books on evolutionary theory all seem to take for granted the fact that students find evolution easy to understand when actually, from a psychological perspective, it is a rather counterintuitive idea. Evolutionary theory, like all scientific theories, is a means to understanding the natural world. Understanding Evolution is intended for undergraduate students in the life sciences, biology teachers or anyone wanting a basic introduction to evolutionary theory. Covering core concepts and the structure of evolutionary explanations, it clarifies both what evolution is about and why so many people find it difficult to grasp. The book provides an introduction to the major concepts and conceptual obstacles to understanding evolution, including the development of Darwin's theory, and a detailed presentation of the most important evolutionary concepts. Bridging the gap between the concepts and conceptual obstacles, Understanding Evolution presents evolutionary theory with a clarity and vision students will quickly appreciate."

Phosphoinositides II: the diverse biological functions
"In two volumes, this book elucidates the crucial mechanisms that control the dynamics of phosphoinositide conversion. Volume II extends into the role of phosphoinositides in membrane organization and vesicular traffic. Endocytosis and exocytosis are modulated by phosphoinositides, which determine the fate and activity of integral membrane proteins. Phosphatidylinositol(4,5)-bisphosphate is a prominent flag in the plasma membrane, while phosphatidylinositol-3-phosphate decorates early endosomes. The Golgi apparatus is rich in phosphatidylinositol-4-phosphate, stressed cells increase phosphatidylinositol(3,5)-bisphosphate, and the nucleus has a phosphoinositide metabolism of its own. Phosphoinositide-dependent signaling cascades and the spatial organization of distinct phosphoinositide species are required in organelle function, fission and fusion, membrane channel regulation, cytoskeletal rearrangements, adhesion processes, and thus orchestrate complex cellular responses including growth, proliferation, differentiation, cell motility, and cell polarization."

Phosphoinositides I: enzymes of synthesis and degradation
"In two volumes, this book elucidates the crucial mechanisms that control the dynamics of phosphoinositide conversion. Starting out from phosphatidylinositol, a chain of lipid kinases collaborates to generate the oncogenic lipid phosphatidylinositol(3,4,5)-trisphosphate. For every phosphate group added, there are specific lipid kinases – and phosphatases to remove it. Additionally, phospholipases can cleave off the inositol head group and generate poly-phosphoinositols, which act as soluble signals in the cytosol. Volume I untangles the web of these enzymes and their products, and relates them to function in health and disease. Phosphoinositide 3-kinases and 3-phosphatases have received a special focus in volume I, and recent therapeutic developments in human disease are presented along with a historical perspective illustrating the impressive progress in the field."

Molecular theory of the living cell : concepts, molecular mechanisms, and biomedical applications
"The book presents the first comprehensive molecular theory of the living cell ever published since the cell doctrine was formulated in 1838-1839. It introduces into cell biology over thirty key concepts, principles and laws imported from physics, chemistry, computer science, linguistics, semiotics and philosophy. The author formulates physically, chemically and enzymologically realistic molecular mechanisms to account for basic living processes such as ligand-receptor interactions, enzymic catalysis, force-generating mechanisms in molecular motors, chromatin remodelling, and signal transduction. Possible solutions to basic and practical problems facing contemporary biology and biomedical sciences have been suggested, including pharmacotherapeutics and personalized medicine. "

The boreal owl: ecology, behaviour, and conservation of a forest-dwelling predator
""Widespread in North American forest regions including the Rocky Mountains, the Boreal Owl (Aegolius funereus) was once the most numerous predatory bird in Eurasian boreal forests. Synthesising the results of unique long-term studies of Boreal Owls, this book explores hunting modes, habitats and foods, prey interactions, mating and parental care, reproduction, dispersal, survival and mortality, population regulation and conservation in boreal forests. Providing a detailed introduction to the species, the authors study the complex interactions of Boreal Owls with their prey species. They examine the inter-sexual tug-of-war over parental care, and the behavioural and demographic adaptations to environmental conditions that predictably and markedly fluctuate both seasonally and multi-annually. They also question whether Boreal Owls are able to time their reproductive effort to maximise lifetime reproductive success. Discussing the effect of modern forestry practices on owl populations, the book also examines how Boreal Owls could be managed to sustain viable populations"--
