Kaos Öksüz Kaldı: Edward Lorenz Anısına
Published on April 18th, 2008.

Kaos Teorisi’ni ortaya atan meteorolog Edward Lorenz geçtiğimiz çarşamba günü (15.04.2008) uzun süredir cebelleştiği kanser hastalığına yenik düşerek 90 yaşında vefat etti. Kaos öksüz/yetim kaldı…
Kaos Teorisi’nin (Chaos Theorem) deterministik fizik dünyasını sallamağa başlayacağı andı… MIT‘de Meteoroloji profesörü olan Edward Lorenz’in bir kelebek kadar ufacık bir canlının Brezilya’da kanatlarını çırpması ile Texas’ta kasırgalar koparabileceğini gösterdiği an herhalde herkes şaşkınlıktan ağzı açık bakmıştır. Newtoncu determisitik fizik dünyasından çıkıp biraz farklı düşündüğümüzde; küçücük, ufacık bir etkinin nasıl olup da devasa etkilere sahip olabileceğini tahayyül ettiğimizde insanın doğaya olan bakışı baştan aşağı değişebilir ölçüde.
Meteoroloji alanında bir ödül olmadığı için kendisinin bir Nobel Ödülü yok. Ancak Temel Bilimler 1991 Yılı Kyoto ödülüne sahip… Aynı ödül komitesinin yorumu ie şöyle “İnsanlığın doğaya bakışında Sir Isaac Newton‘dan bu yana en dramatik değişimlerden biri”…
Günümüz dünyasında oldukça can sıkıcı bir kavram kargaşası mevcut. Kaos kelimesi bugünün basınında ve sokaklarında sadece kargaşa ve arbedeyi betimlemek için kullanılıyor. Bu durumun böyle olmadığını Kaos hakkında bir miktar araştırma ve okuma yaparak anlayabilirsiniz. Bu işe de Fritjof Capra‘nın “The Web of Life” (Yaşamın Örgüsü) isimli kitabı ile başlayabilirsiniz. The Web of Life’ın, Prof. Dr. Beno Kuryel tarafından yapılmış Türkçe tercümesi de mevcut. Eğer İzmir’de oturuyorsanız, Prof. Dr. Beno Kuyel’in “Bilim Felsefesi Sohbetleri”ne katılmanızda büyük fayda olacağı kesindir. Ayrıca çok değerli fizikçi Ilya Prigogine‘in “Order Out of Chaos” (Kaos’daki Düzen) ve James Gleick‘in “Chaos” (Kaos) adlı kitaplarını mutlaka edinin.
Bugün deterministik fizik anlayışının etkileri her yerde görülüyor… Felsefeden koparılmış bir bilim, politika üretemeğen bir bilim, belirlenimci toplum anlayışı… Edward Lorenz’e ne kadar teşekkür etsek azdır. Bir “Lorenz Attractor“‘u (Çekicisi) ile veda edelim, çok teşekkürler, çok!

Books #8: Biotransformations and Bioprocesses
Published on March 18th, 2008.
From the laboratory to full-scale commercial production, this reference provides a clear and in-depth analysis of bioreactor design and operation and encompasses critical aspects of the biocatalytic manufacturing process. It clarifies principles in reaction and biochemical engineering, synthetic and biotransformation chemistry, and biocell and enzyme kinetics for successful applications of biocatalysis and bioprocess technologies in the food, chiral drug, vitamin, pharmaceutical, and animal feed industries. Studying reactions from small to supramolecules, this reference provides an abundant display of end-of-chapter problems to sharpen understanding of key concepts presented in the text.[link]
Editorial review:
Isa very helpful reference text for the scientists who want to understand the bio-transformations and the bio-processes supported them involved in the production of complex, valuable and ecological compounds and discuss the advances of the bio-technologies in the future. cover the major aspects of biotransformations and bioprocesses, from the viewpoint of the specific phenomena and processes involve in the production of bioactive compounds, being useful to the scientists interested on biotechnology fundaments and perspectives. Professor Dan Cascaval, Technical University GH Asachi of Iasi, Faculty of Chemical Engineering, in Iasi Polytechnic Magazine, Vol. 17, No. 1 / 4, March/December 2005 concise yet comprehensive, covering chemistry and engineering aspects of biotransformation and giving an overview of the various steps involved during the transition from a lab to the plant. This book has illustrations, homework problems, and innovative extensions. This approach will encourage students to obtain a more in-depth understanding of key scientific and engineering concepts.

Journals #1: Yeast
Published on March 4th, 2008.
Yeast had a facelift and revision in aims and scopes.
Wiley Interscience promotion as follows:
Revised aims and scopes
Yeast publishes original research articles and reviews as well as short communications on all aspects of Saccharomyces and other yeast genera, including clinically important yeasts. Covering topics from genetics and molecular biology through to ecology and taxonomy and focusing on the most significant developments of research with unicellular fungi, this journal really is essential reading for those wanting to keep in the know about this rapidly moving field.

Articles #2: A Novel, Killed-Virus Nasal Vaccinia Virus Vaccine
Published on February 29th, 2008.
Nanoemulsion vaccines and HIV
Today I was surfing for the vaccines, I suddenly saw a recent study on smallpox protection which has been published in Clinical and Vaccine Immunology… Looks very promising towards to a new HIV vaccine. Check it out…
Ref: “A Novel, Killed-Virus Nasal Vaccinia Virus Vaccine” (Clinical and Vaccine Immunology, p. 348-358, Vol. 15, No. 2).

Live-virus vaccines for smallpox are effective but have risks that are no longer acceptable for routine use in populations at minimal risk of infection. We have developed a mucosal, killed-vaccinia virus (VV) vaccine based on antimicrobial nanoemulsion (NE) of soybean oil and detergent. Incubation of VV with 10% NE for at least 60 min causes the complete disruption and inactivation of VV. Simple mixtures of NE and VV (Western Reserve serotype) (VV/NE) applied to the nares of mice resulted in both systemic and mucosal anti-VV immunity, virus-neutralizing antibodies, and Th1-biased cellular responses. Nasal vaccination with VV/NE vaccine produced protection against lethal infection equal to vaccination by scarification, with 100% survival after challenge with 77 times the 50% lethal dose of live VV. However, animals protected with VV/NE immunization did after virus challenge have clinical symptoms more extensive than animals vaccinated by scarification. VV/NE-based vaccines are highly immunogenic and induce protective mucosal and systemic immunity without the need for an inflammatory adjuvant or infection with live virus.

Books #7: Principles of Tissue Engineering
Published on February 25th, 2008.
First published in 1997, Principles of Tissue Engineering is the widely recognized definitive resource in the field. The third edition provides a much needed update of the rapid progress that has been achieved in the field, combining the prerequisites for a general understanding of tissue growth and development, the tools and theoretical information needed to design tissues and organs, as well as a presentation by the world?s experts of what is currently known about each specific organ system. This edition includes greatly expanded focus on stem cells, including adult and embryonic stem cells and progenitor populations that may soon lead to new tissue engineering therapies for heart disease, diabetes, and a wide variety of other diseases that afflict humanity. This up-to-date coverage of stem cell biology and other emerging technologies is complemented by a series of new chapters on recent clinical experience in applying tissue engineering. The result is a comprehensive textbook that we believe will be useful to students and experts alike.[link]
